Kde 4.9.3 no preview for pdf files in dolphin ?

I have poppler and poppler-qt installed but still I dont see option to turn on preview for pdf files.

You need to install kdegraphics-thumbnailers, then enable PDF preview in dolphin configuration (General > Preview)

Since 10.4.6 Update: "ATSServer" with high CPU-usage when opening PDFs

Since I've updated to 10.4.6 my system is very slow when I open PDFs (in "Preview" or "Acrobat").
This is caused by the process "ATSServer" which goes through every file in "~/Library/Fonts" (I have over 4.800 files there - but just a view are activated by "FontBook") and so it takes very high CPU-usage.
I didn't have this problem bevore the update and I didn't make any changes on my font settings.
I've cleaned the font cache, but it doesn't help.
Any ideas?

I haven't noticed any change myself, Dan, but I have the 2 GHz model.
One thing I HAVE noticed though after OS updates is that they can often result in a fair amount of file and free space fragmentation immediately after installation. OSX's routines will deal with fragmentation of small files , but not of large ones (over 20 Meg), and it won't deal very effectively with free space fragmentation. If your HD is getting full this can cause significant slowdowns, especially where video is involved.
You should also run DiskUtility and check for any directory and permissions issues.

Safari webpage preview fetcher high CPU usage, runs hot Macbook Pro, fan

Even when turned off in Safari Preferences, safari webpage preview fetcher starts up and starts using high CPU % (99.8% when checked on Activity Monitor!). Macbook starts running hot, fan starts running on high. You can force quit safari webpage preview fetcher in Activity Monitor, but it starts itself back up again!

Well, I disabled safari webpage preview in preferences, and rebooted, zapping the pram and it hasn't restarted, and I haven't had the high fan / hot running so yay!

Kernel task over 100%. High CPU Load. High Temp. Problem Solved.

Hi,
I thought i would make a post as i had been having trouble with my 13 inch mid 2009 MBP for sometime (6 months), with runaway kernel tasks causing high CPU loads. I had searched through forums and discussions for a long time trying to find the problem and isolate it. Initially i discovered some problems with finder preferances that were chewing up CPU which i solved by deleting the prefereance file, allowing the system to recreate a non corrupted version. This helped but still i had problems. I tried maintainance suites like onyx, reseting PRAM, booting into safe mode, hardware checks and diagnostics, and more little tricks than i can remember. Nothing i tried really seemed to make a differance. Through reading on this forum and others i found out the kernel tasks can be a direct result of hi CPU core temps as the system runs a lot of small kernel tasks to try and take some of the CPU load away from processor intensive processes that may be contributing to hi CPU load. The thing which solved my problem in the end was opening up my MBP, being careful not to touch the logic board and literally puting my vacuum cleaner over the fan, sucking dust and dirt and dust out of my latop. This computer has been through the dirt with me, literally its been dragged through rural south east asia for a year and accompianied me to warhouse parties to perform and run lighting and visuals. Its little wonder the fan was obviously clogged. I know people tend to be holier than though with their mac products and treat them with the upmost respect, but my love for the MBP has come from how sturdy and reliable it has been under less than desirable conditions.
Now im not telling people this is what they should do, i had just noticed alot of people with this problem in my attempts to solve mine, and in the end this is what helped. My MBP now runs at a temperature where i can touch the metal near the CPU without being worried about a 3rd degree burn and the CPU load is acceptable with no run away kernel tasks. Like i saw this might not be the cause of your porblem, as my laptop has lived a rough and fun life so far, but i thought i would share this with you all as i have had contstant help from this forum and others searches for solutions to problems with my apple products.

Already tried SMC and PRAM-reset with no luck.
On my MacBook late 2008 it's the same effect.

[SOLVED] qemu-kvm high cpu usage when using pulseaudio alsa-plugin

My Arch system is configured to use pulseaudio. When an application connects to the sound server it will use either a native pulseaudio driver, or the pulseaudio alsa-plugin if it using a alsa driver.
qemu-kvm in 'extra' is not compiled with native pulseaudio support. When running guests with sound hardware support, qemu-kvm connects to the sound server using the pulseaudio alsa-plugin.
The problem I'm seeing is high cpu usage on the Arch host even though cpu usage on the guest is low. Also, the guest is often unresponsive for a period of time when opening sound applications like the mixer or playing audio.
My solution is to recompile qemu-kvm with native pulseaudio support. This eliminates the use of the pulseaudio alsa-plugin on the Arch host and fixes the above problems.
An easy was to do this is run:
yaourt -S qemu-kvm --build
And edit the PKGBUILD changing the line:
--audio-drv-list=alsa,sdl,oss,esd \
To:
--audio-drv-list=pa,alsa,sdl,oss,esd \
Finish building and install. Don't forget to add yourself to the kvm group.

Problem disappeared.
I'm not sure, but i think installing xf86-video-modesetting helped to fix this issue.
I had an error messages in /var/log/Xorg.0.log like this:

High CPU load and com.apple.ImageCaptureExtension2 crash after upgrade

After upgrading my Macbook Air from Lion to Mountain Lion, the system has a very high cpu load, and the crash reporter is the process that causes thee high load. In the error log I see this entry several times per second:
17.08.12 12:58:46,011 ReportCrash[5998]: com.apple.message.domain: com.apple.crashreporter.writereport.crash
com.apple.message.signature: Image Capture Extension

com.apple.message.signature3: 03A96CBDA3C85A114383537BFC5C8999
com.apple.message.result: NO
com.apple.message.summarize: YES
I investigated a bit more and recovered, that it has something to do with the printer drivers. When I remove all printers from setting, everything is fine. As soon as I add a printer (Brother MFC 9440CN printer/scanner, printer driver provided by Mountan Lion), the crash reporter starts it's work and the error log is full of those entries.
Any suggestions?
Thanks in advance,
Marcus

I did more exploration and found the cause of this, but I don't know how to fix it:
I removed all Brother and Lexmark printer drivers and rebooted (and also tested with a virtual machine using 10.8.0 as guest os that never had any printer installed). As soon as I enter the printer settings and press the "+", the crashes begin, so it looked like the bonjour one of the printers announcing themselves via Bonjour were causing this.
When watching a picture in the preview app the same happend. We have two multi function printers in our network, the already mentioned brother printer and a Lexmark X204N. Switching off the Lexmark (which wasn't installed on my Mac) solved the problem. Switching off the printer is no solution in our office (it's our fax device and main printer), but switching off mDNS on the Lexmark also solved it. But this can only be a workaround.
Is this a known problem with Lexmark devices and Mountain Lion (it works fine with machines using Lion)? Are there any fixes known? It's just the Lexmark device announing itself via Bonjour that causes trouble, even if the driver is not installed.

Settingsynchost.exe high Cpu usage

Hello Everybody,
So lets get to the point.I clean installed Windows 10 Tech Preview Build 9841 x64 on my Hp pavilion g4 1303-au laptop
Specs of my laptop :
Amd a4-3330mx Radeon HD 6480g Microprocessor
6 GB DDR3 Ram 1333 Mhz
500 GB HDD
what i found problematic in this build (ie.,build 9841) was that when i first boot my laptop after clean install,i opened my task manager and found that Settingsynchost.exe was using 25-35% of cpu without doing anything.My fan was throttling so fast than
normal.I was really so pissed off with that so i retrieved back to my old win8.1 pro x64.So can anyone tell me how to fix this Settingsynchost.exe bug from tech preview because i want to see more aspects of window 10 and give my utmost regards for it.
Thank You
Sincerely,
Aman Srivastava

We have found that the information bubbles that open up in the top right hand corner of pdf documents can consume a lot of CPU, when visible for a user on our RDS servers Acrobat Reader would consume anything between 14-25% of CPU resource. This turned out to be very easy to resolve - first you can simply close the info bubble as the user, this setting is then retained for the next time any pdf documents are open. However this was not a suitable fix for the several hundred users that we have regularly connected to our various RDS farms. Instead we added the following registry settings to each users profile via our logon scripts - these disable the info bubbles and therefore prevent the high CPU usage.
KEY = HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\11.0\AVGeneral
DWORD = bReaderShouldShowInfoBubble
VALUE = 0
DWORD = bReaderShowEPDFToolsPaneInfoBubble
VALUE = 0
I hope that this information helps other users with similar High CPU issues when running Acrobat Reader.

Attn: ALL APPLE PORTABLE OWNERS -Macbook Pro, MacBook Air Apple portable slowdown / kernel high CPU solution

Attn: ALL APPLE PORTABLE OWNERS -MacBook Pro, MacBook Air, Mac mini slowdown kernel / high CPU use problem and solution.
YOU COULD FRY YOUR COMPUTER IF YOU DO NOT FIX THIS PROBLEM SO PLEASE READ THIS ENTIRE MESSAGE!
YOUR MAC WILL THANK YOU
Hey all.
Like many of you I've got a newer Apple portable which slows down to an unusable level for an unknown reason. In my case a 13" mid 2009 Intel MacBook Pro Core 2 duo laptop. After many failed attempts to figure out what this nutty problem is I have discovered the problem, the solution and I have solved this for my own MacBook Pro. Since this fix it has been working immediately and consistently -without issue
I am sharing this with you in hopes that you to can fix your Apple portable yourself or so you know what to tell the Apple techs so they can quickly fix your Mac from this wacky and unfortunate kernel CPU hogging problem.
User Software Symptoms :
Your Apple portable computer periodically for an unknown reason slows down making everything frustratingly slow. This happens even when running previous apps that were never a problem; things that your Mac should be able to handle easily but for some reason now it can't.
Slowdown most often happens during high CPU use such as gaming, video playback/editing, etc. or when running multiple apps (even non CPU intensive apps) at the same time.
Possible Hardware Symptoms:
Your computer is making more noise than it did previously.
Your computer occasionally makes more noise but then gets quieter.
Your computer is always extremely quiet (too quiet) even during high CPU apps -worst case scenario.
It feels hotter than it normally does. Test: After several minutes of the slowness/high kernel CPU touch the computer to feel if it's hotter than normal.
Looking at Activity Monitor (in the Utilities folder) shows the kernel_task is going bonkers eating up CPU but you have no idea why.
After trying many different things to solve this problem such as :
PR ram reset, SMC reset, fresh OS install of 10.5 and 10.6 on external hard-drives, calling and speaking to various Apple tech people who had no ideas/solutions, etc. I had no luck.
Btw, if you're having the symptoms I've decscribed above I would not run the Apple Hardware check (read below as to why). You could fry your Mac!
After much testing I found the problem :
It is my belief that "recent" Apple portable computers are using low quality internal fans which soon stop working!
Fail time period seems to be about 1.0 years to 2.5 years of use but this fail rate could vary depending on use.
First noticeable symptoms (depending on what you notice) could be computer slowdown or your fan is making more noise than it normally does. This is your fan's lubrication slowly eroding making your fan spin slower and less smooth resulting in the louder noise and slower rpm spin speed. The slower fan spin speed means less cooling is happening for your computer. The effect on your computer is that the CPU and other chips are heating up! Overheating to be more specific. When your computer's chips overheat they get wonky and screw things up. Most often this seems to have the effect of making the kernel hog CPU resulting in a frustratingly slow user experience! Heat kills computer chips and it is extremely bad for them. Extreme overheat or repeated overheating has been said to shorten the life of computer chips or in extreme cases even fry them completely!
The longer this goes on without being fixed your fan loses more lubrication and spins slower and slower cooling lesser and lesser resulting in your CPU heating up more and more possibly shortening the life of your Mac! Eventually your fan will stop completely and you could fry your chips! My fan stopped completely and my MBP was running very quietly, too quietly. Luckily I did not fry my chips because I was avoiding using high CPU apps because I knew something was wrong due to the massive slow down and wonkiness when I'd run them.
Side Note:I'm a bit concerned about all those Mac mini servers which may be using the same defective low quality fans which cannot be easily serviced by their owners as they are co-located in some server facility. One positive thing is those facilities are usually well airconditioned keeping temps low.
I suggest you do not run the Apple hardware test if you suspect your computer is overheating because the hardware test can seriously heat up your Mac! I tried running this test and my Mac got so hot I had to shut it down forcefully and I was concerned I damaged the chips. If you want to run the Apple hardware check make sure your CPU temperature is ok and that your fan works well before you run the test.
IF YOU DON'T FIX THIS PROBLEM YOU COULD FRY YOUR COMPUTER DUE TO HEAT DAMAGE!
DO NOT IGNORE THIS PROBLEM YOUR MACS LIFE MAY DEPEND ON IT!
First you need to properly diagnose this problem and see if your CPU is getting to hot and you need to see if your fans are spinning at high rpms giving proper cooling, or if they are spinning at low rpms when running high intensive apps as your CPU temp increases.
TEST IF YOUR FAN(s) IS WORKING CORRECTLY :
Unfortunately Apple does not include CPU temperature reading software nor fan rpm speed software that I am aware of.
However, There are two free ways that I know of to check your CPU tempurature and your fan speed :
One app shows fan speed, and CPU heat, etc.
One app shows fan speed, CPU heat and allows you to adjust your fan speed settings.
One app is a dashboard widget, the other is a system preference.
I suggest you download both of these to check your computer statistics.

http://www.islayer.com/apps/istatpro/
http://fan-control.en.softonic.com/mac
I am not exactly sure what proper CPU temperatures are for the different Apple computers and this will change given different CPU loads.
My MBP doesn't seem to function properly with anything around 90 degrees or higher (celcius).
It seems when the fan is operating normally the CPU temp should not stay above 78 degrees even under heavy load, at least with the apps I'm running in the room temperature I'm in.
I can post back later with more specific temps under longer load, etc. but I wanted to get this post up for people to read as soon as possible so they don't fry their Macs.
If a bad fan is your problem :
THERE ARE ONLY TWO SOLUTIONS FOR THIS PROBLEM :
Fix or replace your fan so it cools the CPU and other chips properly.
I fixed my fan myself and I didn't need to buy a new one. Total cost was about $8.00 because I had to buy a #00 sized screwdriver and had it shipped to me. Price includes shipping.
On my mid 2009 model MacBook Pro fixing the fan was incredibly easy :
Before I started doing this I wasn't 100% this was the problem so I decided to try to fix my fan instead of ordering a new one and replacing it. As it turns out I didn't need a new fan, I only needed to clean the existing fan and relube it's axl so it could spin easier like when it was new. It also didn't make sense to buy a brand new fan from an Apple authorized parts reseller selling me the same low quality fan for $49.00 which would probably fail in 2 years again. Prices for new comparable fans from different manufactures range from about $15.00 USD + shipping to around $49.00 USD + shipping depending on where you order them from and what brand you get.
How to fix / replace your internal fan on a mid 2009 MacBook Pro :
Please note : I am not a hardware technician, nor expert. If you decide to fix your Mac yourself you do so at your own risk through no fault of my own. Prior to opening up your Mac you should google around and learn how to do it correctly and safely so you won't damage your Mac. For example, it is possible for you to damage your Mac by static electricity from your body. To avoid this I believe proper procedure is that you wear a 'ground strap' (around your wrist) which you clip to your Mac's metal body so your body will not excude a charge into your Mac. I believe the idea here is to keep your body's charge level and your Mac's similar. Since I do not have a ground strap and fixing/replacing the fan doesn't require touching any chips I did not wear a ground strap during my fan fix. What I did was periodically repeatedly touch the metal case of my MBP hoping that would be enough and it was. Avoid unecessary actions that can build up a static charge in you. Once I started the repair I did not walk around the room building up an electrical charge in my body. Walking on carpet can often build up a large charge in us so it is better to be avoided while working on your Mac. Certain clothing can build up static charges. Combing hair, etc. If you need to get up from your repair when you come back make sure you first touch the Mac's metal case and not anything inside.
Now that we're done with the scary paranoia, below you will find some instructions on how I fixed my MBP's internal fan
Before you begin:
Check out someone's video (not mine) on how to remove / replace the fan (but not take it apart and repair it):
http://www.youtube.com/watch?v=AghE9newvbs
Check out someone's web page (not mine) on how to replace the fan in a mid 2009 MacBook Pro:
http://www.ifixit.com/Guide/Installing-MacBook-Pro-13-Inch-Unibody-Mid-2009-Fan/ 1338/1
How to repair your mid 2009 MacBook Pro fan:
Make sure you are in a 'secure' environment. No pets, no kids running around, no drinks near the Mac, etc.
Make sure your computer is unplugged from it's power supply and turned off. NOT slept. Totally off / powered down.
1. Get a size #00 phillips screwdriver (Hobby store, Radioshack, Amazon).
2. Open up your MBP by unscrewing the bottom (yes flip it over so it's resting upsidedown). Note where each screw goes because some are different lengths. I placed each one around my MBP where they go, insuring I know their order (don't jumble them up). Note which direction your MBP is facing when it's upside down so if you spin it around while working on it you still know where the screws go.
2b. Some recommend removing the MBP's battery but I didn't do this step. You probably should, just to be safe. Follow the online instructions from the web page I listed about disconnecting the battery.
3. Unscrew the fan's 3 holding screws.
4. Unplug the fan's electrical connection (lift it straight up off the board). If you need to you can try to pry it up while you lift with a non metal/non electrical conductive object like a spudger if you have one or -perhaps a pen cap. Before you remove it, look closely at how it's attached so when you put it back on you won't wonder if you're doing it correctly. There's only one way it can go because it cannot fit 'the wrong way' but looking at it closely will make you feel more confident popping it back on when the time comes.
5. Remove the fan - it easily lifts out.
6. Take the fan apart by unscrewing it's one screw then unlatching the plastic clips which hold it together.
7. Seperate the fan blades from the housing. Lift the fan blades off of the fan housing by pulling it straight out away from the housing.
8. Clean off the dust that's gathered. A can of compressed air helps here (I didn't have one). I used a little brush from my electric shaver kit which worked well. Once you've removed all the dust from the fan and surrounding areas proceed to the next step.
9. Reapply new lubrication. You need less than 1 drop. Be sure it covers the entire fan blade axl as this is what needs to be well lubricated. Make sure there isn't excess oil that will fly around when the axl/fan spins at high rpms. I used the only oil I had which was olive oil (for cooking!) but I do not suggest this. At the time I was doing this I didn't know my fan was the problem so I wasn't even sure I was going to relube it. You should probably use something more appropriate perhaps like 3 in 1 oil. A good idea would be to call the manufatures of these little fans and ask them. Maybe a hobby store knows of good lubricants for these purposes?
DO NOT use things like WD 40 as it's not a long term lubricant or so I've read.
10. Once your fan is now clean and oiled (make sure there isn't too much oil) reassmble the fan.
Push the fan blades/axl back into the housing shaft. Give it a few spins with your finger.
Screw together the fan housing then reclip the clips.
11. Place the now reassembled fan back into your Mac and screw it in place (3 screws).
12. Reattach the fan's electrical wiring by gently pushing it into place. Make sure you've got the right end facing down before you push it in place.
13. Once your Mac's internals are clean and reassembled, place the rear cover back on your Mac and screw it in place.
14. Double check you didn't forget anything like screws, tools, etc.
15. Boot up your Mac and monitor the temperature and fan speed using those programs.
Compare the previous temps/fan speed to the current temp/fan speed.
Run a high CPU intensive app where your computer has been slowing down.
You should now have a happy Mac
If you have this problem and this solution fixed it for you please post in this thread letting me and everyone else know!
Hope that helps.

Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

Performance issue with high CPU and IO

Hi guys,
I am encountering huge user response time on a production system and I don’t know how to solve it.
Doing some extra tests and using the instrumentation that we have in the code we concluded that the DB is the bottleneck.
We generated some AWR reports and noticed the CPU was in top wait events. Also noticed that in a random manner some simple sql take a long time to execute. We activated the sql trace on the system and noticed that for very simple SQLs (unique index access on one table) we have huge exec times. 9s
In the trace file the huge time we had it in fetch area: 9.1s cpu and elapsed 9.2.
And no or very small waits for this specific SQL.
it seems like the bottle neck is on the CPU but at that point there were very few processes running on the DB. Why can we have such a big cpu wait on a simple select? This is a machine with 128 cores. We have quicker responses on machines smaller/busier than this.
We noticed that we had a huge db_cache_size (12G) and after we scale it down we noticed some improvements but not enough. How can I prove that there is a link between high CPU and big cache_size? (there was not wait involved in SQL execution). what can we do in the case we need big DB cache size?
The second issue is that I tried to execute an sql on a big table (FTS on a big table. no join). Again on that smaller machine it runs in 30 seconds and on this machine it runs in 1038 seconds.
Also generated a trace for this SQL on the problematic machine:
call     count       cpu    elapsed       disk      query    current        rows

latch: object queue header operation            1        0.00          0.00
********************************************************************************The high CPU is present here also but here I have huge wait on db file scattered read.
Looking at the session with the select the AWG_wait for db scattered read was 0.5. on the other machine it is like 0.07.
I though this is an IO issue. I did some IO tests at SO level and it seems like the read and writes operation are very fast…much faster than the machine that has the awg_wait smaller. Why the difference in waits?
One difference between these two DBs is that the problem one has the db block size = 16k and the other one has 8k.
I received some reports done at OS level on CPU and IO usage on the problematic machine (in normal operations). It seems like the CPU is very used and the IO stays very low.
On the other machine, the smaller and the faster one, it is other way around.
What is the problem here? How can I test further? Can I link the high CPU to low/slow IO?
we have 10G on sun os with ASM.
Thanks in advance.

Yes, there are many things you can and should do to isolate this. But first check MOS Poor Performance With Oracle9i and 10g Releases When Using Dynamic Intimate Shared Memory (DISM) [ID 1018855.1] isn't messing you up to start.
Also, be sure and post exact patch levels for both Oracle and OS.
Be sure and check all your I/O settings and see what MOS has to say about those.
Are you using ASSM? See Long running update
Since it got a little better with shrinking the SGA size, that might indicate (wild speculation here, something like) one of the problems is simply too much thrashing within the SGA, as oracle decides "small" objects being full scanned in memory is faster than range scans (or whatever) from disk, overloading the cpu, not allowing the cpu to ask for other full scans from I/O. Possibly made worse by row level locking, or some other app issue that just does too much cpu.
You probably have more than one thing wrong. High fetch count might mean you need to adjust the array size on the clients.
Now that that is all out of the way, if you still haven't found the problem, go through http://oracle-randolf.blogspot.com/2009/02/basic-sql-statement-performance.html
Edit: Oh, see Solaris 10 memory management conflicts with Automatic PGA Memory Management [ID 460424.1] too.

High CPU Usage On client application when upgrade remote SQL database

Hi,
Is anyone here encountered very high CPU usage after upgraded the database from SQL 2005 to SQL 2012? Following describes my issue.
I have my client application running on Windows 7 that access to central database (SQL 2005) on Windows server 2003 using ODBC connection, this client application basically query data and perform data insert and update. There are a number of this similar
clients connected to the database.
Due to slowness of the database server, company decided to upgrade the database server to SQL 2012 and also new hardware runing Windows Server 2012. There is no change on the client application and client hardware and the client application still using the
same ODBC connection to query, insert or update the new database server.
The problem I am now experiencing now is that my client PC where my client application running the CPU usage is very high almost hitting 100% when accessing to the central database. I am also noticed this program lsass.exe that utilized almost 40-50% of
the CPU time when client application accessing the central database.
Is anyone here know, why client PC CPU usage 100% when access to upgraded SQL 2012 database? What is lsass.exe program doing, it only appear when accessing to database server. How to reduce the CPU usage on client?
Thanks.
Chee Wee.

Hello,
After upgrading, please rebuild indexes and update statistics on the databases.

High CPU usage - Rapid Battery Drain - Running HOT

Looking for help.. PLEASE!
Z10 - Model STL100-3 Software release 10.2.1.2179
Symptoms;
Occasionally, and for no apparent reason, I notice my Z10 getting hot in my pocket. I run the device monitor App and see a very high CPU usage, which consequently drains the batter very quickly.
I've tried all the solutions from every support group thread and blog. And I mean ALL!
Pulling the battery
Replaced the battery
Removed the SIM
Deleted G Mail
Removed all 3rd party Apps (2)
Stopped email sync
Stopped calendar sync
Turned off all radio
Turned Off Wi-Fi
Let it sit for hours, even days to let it finish doing whatever its trying to do
Etc Etc Etc.
Finally, I called BB support, they wanted $50 to talk to someone. I told them the issue, they said the device is bad and must be replaced. I said its software related!! They said.. no, its a hardware issue. Device is under warranty and they want me to just go get a new one. I don't want a new one, I want a fix! Stop the waste of BB $
Temporary solution
Eventually, I decided I would do a restore, back to the factory settings, and here's when I found something
I run BB Link, connect the device, do a back-up... and LOW AND BEHOLD.. this fixes the high CPU usage and the device runs great, very cool, low cpu and extremely long battery life.
Sadly! .. this problem reoccurs, after a few days, sometimes after a couple of weeks and just out of the blue.
I can force this fault to occur, simply by doing a restart of the device. Sure enough, it will run hot, use all the cpu and I will have to do a back-up to get it to settle down again. I've tried to wait for the so called 'indexing' to finish, but it never stops running with high cpu and doesn't help.
Can any one tell me whats happening and how to make this a permanent fix?
There are hundreds if not thousands of people having very similar issues, and many different methods to fix it. Its my belief that there is an underlying bigger problem that relates to all these differing fixes, but as yet.. I cant find it and none of these fixes work for me. For now... I will keep doing the occasional back-up and hope I get a response that can help.
Thanks to all that read this.

The heat may be normal. After a little water damage incident, which I repaired, I disassembled my Z10 the find a small heat sink will thermal compound. This helps dissipate heat efficiently. I found a large number of air bubbles and possibly a large air pocket by the way the paste stuck to both sides. I removed the old paste and replaced it with artic silver paste and the z10 has been much much cooler. It use to run about 105*f and now it is around 85*f.
See this thread I posted for before and after pictures using a thermal imager.

@Curve8530 .....as much a s your discovery is appreciated, I hardly believe that most people will actually dismantle their phone to remove the paste and replace with arctic silver. Besides, what you are doing is not a fix for the actual problem....
In most cases, this heat is associated with apps using the CPU resources beyond the normal limits.
As an easy fix, finding and removing the app(s) in question followed by a reboot, solves the issue. In some cases an OS reload is necessary.... but under no circumstances I would even remotely suggest to any member to dismantle their phone and do what you did...

PDF preview in windows 8.1

I am facing a problem previewing PDF file from my application.
It was working find in windows xp and windows 7 machines, but showing error line "Error HRESULT E_FAIL has been returned from a call to a COM component" in windows 8.1 machine.
my application using "Adobe PDF preview for Vista" for PDF preivew.
i think my previewer is causing the problem, but dont know which preview handler me to use instead of "Adobe PDF preview Handler for vista"
please help me to solve this
ps: from my windows explorer i can see pdf preview.
Thanks
Rosh

After a close debug, i found that "doPreview" is crashing my application. Also the previewer assembly "PDFPrevHndlr.dll" is modified in Adobe Acrobat XI.
the modified "DoPreview" method now expecting 2 parameter (int, out int), after giving some values in it, it stops crashing, still my PDF preview not shown up.

Yet another high cpu using flash issue

Salutations. What I'm about to tell you won't come to you as a surprise as there have been many similar topics discussed here. In fact, on the first page, there were two. So let's get on with it!
hp pavillion entertainment notebook dv6 e2170ee
windows 7 64bit
6gb ram
intel core i7 cpu q 720 @ 1.60 GHz    (never overclocked. don't know how to)
nvidia geforce gt 230m
firefox is on safe mode. kind of better than regular mode.
firefox waaaay better than chrome in handling flash. haven't tried it on ie. don't want to. i left ie8 at version 8
flash hardware accelration is off
firefox hardware accelaration is on
latest flash player enabled
latest shock player enabled
latest flash director enabled
latest firefox
no idea if my vents and cooling system work properly. read several posts about this issue being related to hardware.
i have updated my drivers using hp support assistant, driver detective, and windows update. wouldn't be surprised if there was a conflict with all this nvidia driver as well. went to the site. it detected my model and sent me the driver. had audio and video options in it.
while writing this post, the adobe tab + 4 flash tabs off the same site (youtube, younow, cam sites, etc) are open.
performance tab in taskbar says
flashplayer 15 *32bit (2 processes with the same name but diff cpu usage by the way. why 2?) is using 5%
firefox *32 bit is using 5%
audiodg.exe is nowhere to be found
now firefox and flashplayer keep alternating ofcourse. flash always ends up with higher cpu when everything breaks. i have noticed that even after closing ff, ff and flash are still in the processes table. they stay there for a bit. why?
ISSUE NUMBER 1: i can't play a video and have flash players on at the same time. I'd like to watch a movie and every now and then look to my other screen to see what's going on with the flash site. it can't be done. all is well at the beginning then it goes to hell. i have the latest free version of bsplayer and videolan. Yes vlc handles better but it all goes to hell in the end. sometimes the video won't even show on vlc; only audio
ISSUE NUMBER 2: i don't understand the logic behind the increase in cpu. if i have 6 tabs open all flash all is well. but at some point it just spikes up. so i always try to keep the number of flash tabs as low as possible. sometimes 4 are no issue but 5 are a big issue. sometimes closing a tab helps and sometimes it doesnt.
ISSUE NUMBER 3: audiodg starts using more than 2%. It can go up to 11 or 13 even. That shouldn't happen. I've been told that for it to go beyond 2 or even 3 means there's a conflict. I had trouble dealing with this issue. I don't know what or where the conflict is. So if there's anyone here that's good at this please contact me. Ill post a pic of device manager. For the sound, i have 4 nvideo and 1 idt audio codec. I cdon't know which to disable or uninstall. im thinking of unintalling every audio/video driver i hav and start from the beginning. BUT LETS NOT MAKE THIS ABOUT AUDIO/VIDEO CONFLICT
QUESTION 1: was there ever a time when this issue didn't exist? perhaps there's a "stable" version of ff or flash that don't cause this.
QUESTION 2: ive seen a lot of posts about this but I honestly can't remember any participants saying OH REALLY? ODD, I NEVER HAD THIS ISSUE BEFORE
QUESTION 3: isn't there some kind of tracer that can track the moment that it goes to hell? im sure there is but no one's mentioned it so far
QUESTION 4: would buying a new laptop solve this? I'd like to think not since the issue is flash not the capabilities of a laptop but i can't help but think that a better laptop will fix this. My laptop is 4 years old.
QUESTION 5: i don't know anything about multithreading or multiple cores handling a single process but if someone showed me how, would that resolve my issue?
MY WISH: for flash to coexist peacefully with human beings

Disabling Hardware Acceleration in Flash means that we're doing all of the processing on the CPU, instead of on the GPU. The GPU is purpose-built for 3D graphics and video decoding and is far more power efficient. Decoding H.264 video in software is very CPU intensive, which is why we made the huge investment to enable hardware acceleration on the vast majority of available desktop hardware. Running six CPU intensive tasks simultaneously (which is what you're doing by using six simultaneous tabs) is unsurprisingly going to tax your machine.
If you've disabled Hardware Acceleration because video wasn't working right or something, figuring out how to get that enabled (or moving to better hardware with good driver support) would solve the vast majority of what you're describing here. If HP doesn't offer updated drivers, I'd recommend trying the corresponding Nvidia drivers, as OEMs aren't always motivated to pick up the latest fixes once a model is no longer generating new revenue for them. The chipset manufacturers tend to provide longer support, but those drivers aren't officially supported by the OEM.
The architecture for Protected Mode for Firefox is a result of the fact that we've retrofitted a modern plug-in security approach to a legacy plug-in architecture. As you've noticed, equivalent sandboxing in other major browsers is designed into their plug-in architectures, and is therefore more efficient. We've made huge investments to support modern security architecture and always do our best to accommodate efforts from our partners in the browser space to further secure the browser. You can find a detailed explanation of our approach to Firefox here: Inside Flash Player Protected Mode for Firefox
Firefox controls the instantiation and destruction of Flash instances. You'll also notice that Firefox hangs out for a while after shutdown. This is something that we're aware of, but it's beyond our control.
Flash doesn't have much to do with audiodg, except for the fact that it generates sound and uses the windows sound subsystem. This article seems to present some reasonable advice in resolving issues with high CPU consumption from the sound subsystem. Fix Audiodg.exe High CPU Usage in Windows 7 | Windows EXE Errors
Hardware accelerated video encoding is typically not available on consumer-grade hardware (primarily because of the difference in licensing models for encoding and decoding with popular commercial codecs), and therefore is done on the CPU. The particular website chooses what codecs and bitrates are involved, and higher quality feed will consume more CPU. It's also worth pointing out that not all video can be decoded in hardware. We provide clear guidance to content providers on how to encode video so that it can be played back efficiently, it's ultimately up to the content provider to follow that advice.
So, long story short, each tab consumes resources. Running a single tab is going to use less resources than running multiple tabs. The latest version of Internet Explorer does some stuff to reduce resource consumption in tabs that you're not actively looking at. We're discussing possibilities with the Chrome folks for doing the same thing in Chromium-based browsers. Mozilla isn't interested in investing in browser plug-ins, so we don't expect to see the necessary browser-side improvements there. The Chrome sandboxing model is more efficient that protected mode for Firefox, so tasks that require moving a lot of data (like streaming video) may use less CPU in Chrome.
To answer your questions specifically:
1.) There was a time before we supported multiple tabs, webcam streaming, H.264 video decoding and modern security sandboxing. I wouldn't recommend using those versions.
2.) There are a few posts about this, but we have ~1.5 billion users. The majority of the very small number of folks relative to our install base are complaining their machines are overheating, which is a symptom of an ineffective cooling system.
     There's nothing magic about Flash that causes it to somehow superheat the CPU.
     There was a time before tabs, where people didn't normally run 5-50 browser windows. Websites also got much more complex, and the security threats got far more serious and complex.
     Playing video as a plug-in in the browser as opposed to something like VLC is inherently less efficient, as pretty much each pixel and packet gets passed through the browser before it gets to the OS or drivers.
     All of these things require additional processing. The resources on your computer are still finite, and there is an upper limit to the number of simultaneous tabs you can use.
     At some point, you come to a juncture where you need to decide between throwing more hardware at the problem, or using less tabs simultaneously.
     Also, most laptops have power saving CPUs, so they'll ratchet the clock speed down to save battery. You might want to check your power settings to make sure you're running at the CPU's full capacity when plugged in.
3.) Not that would generate anything really useful.
4.) Possibly. You actually already have a multi-core machine. I think you'd get more bang for your buck by enabling hardware acceleration and switching browsers.
5.) You already have a multi-core machine that we support.
Your Wish: We're constantly addressing security issues identified through our own testing, emerging research and intelligence from our partners in academia, government and industry. We're also looking for opportunities to tune the player, but the reality is that Intel, Nvidia and ATI (and a long list of others, in addition to Adobe) have tuned Flash Player extensively for their hardware. We work closely with the Internet Explorer and Chrome teams to continue to make the Flash experience better, and are always happy to work with the Firefox team should they decide that they're interested in plug-ins and the desktop browser again. At the end of the day, Flash is just a low-level runtime. It's just as possible to write inefficient ActionScript as it is to write inefficient C++, and while we provide some fantastic tooling for profiling your Flash content, it's up to individual content providers to write efficient code. It's really difficult to find opportunities to make generic optimizations that don't break a percentage of the hundreds of millions of sites published with Flash content.
I'm actually still not clear on what the problem you're experiencing is. All software running on your machine that's actively processing something is going to use a non-zero percentage of CPU time. The symptoms you describe indicate that Flash consumes 5% of the CPU, which is totally reasonable. I'm guessing that I don't have the complete story.

Urgent help needed with iPhoto/pdf preview for book order - mysterious pixelated areas show on PDF but not in iPhoto

Hello. I ordered an iPhoto book last week to give to my parents for their 50th wedding anniversary. Tonight, I just checked on the order status and found that my book is cancelled. I received no notification about it, and all I could do was fill out the online form, so customer service will get back to me on Monday via email (if I'm lucky...). There is no telephone number for me to call about this. I decided I'd best do some searching to try to figure out what had happened.
I had thought that the preview I saw in iPhoto was the preview of the book. I found out I was wrong. So I created a PDF preview of the book and found some craziness that I don't understand. In iPhoto (and any other program, i.e. PhotoShop), my photos are fine. They are mostly TIFF format and high resolution with a few high res JPEGs. However, when I view the PDF, there is a band of black and white pixelation about 1/2-inch across the bottom of some pages - not all. The photos in that area are messed up in that band zone. The other photos are totally unaffected. This affects both TIFF and JPEG photos, and both black and white and color.
Has anyone else had this problem, and what was your solution? I would be extremely grateful to anyone for advice or information about this! The anniversary party is less than a week away and I'm beyond my limit of stress right now...

Launch iPhoto with the Option key held down and create a new library. Import enough photos for a book (use some of those in the current book) create a new book and preview as a PDF. If you don't see the problem then it's limited to your library which may be damaged. If that's the case make a temporary, duplicate copy of the library and try the two fixes below in order as needed:
Fix #1
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/Library/Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your Home/Library/Caches/com.apple.iPhoto folder.
3 - reboot, launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding the the Option key. You'll also have to reset the iPhoto's various preferences.
Fix #2
Launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library.
Select the options identified in the screenshot and the option to rebuild the small thumbnails.
Click to view full size
If you get the same problem in the test library then log into another user account on your Mac, create a test library and try it there. If the problem shows up there a reinstall of iPhoto is indicated. To do so you'll have to delete the current application and all files with "iPhoto" in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/ folder,

If you don't encounter the problem in the other user account then it's something in your account that's the culprit. Post back with the results.
