I have CPU usage . 1.5Gb within 1-2 hours of usage. Pls help with troubleshoot
Why does memory keeps non increasing? Can somebody please wok with me or develop some plugin to troubleshoot so that I can submit the log records for somebody to investigate. I am using Firefox 6 with all plugins updated on a Windows Vista 64-bit (i know we only have 32 bit firefox)
I don't see any improvements. 1.7GB of physical memory is used and that just keep on growing. Why? Somebody please help me seriously! I love YouTube and GMAIL more than anything else. I hope that is not a crime for Mozilla..

I have installed oracle 10g in my winxp machine. i am using enterprise manager. i am not able to shutdown the system as it asks for os username and password. i have provided my os username and password but eerror persiste. somebody pls help me to get rid of this.
Here I am using Java Type IV for database
connection.
So,there was no necessity of creating DNS.How your app communicates with db shouldn't matter for the end user. Still, you may want to use a functional network name also for the thin client driver connection string.
So,is there any other way to solve this problem.What is the problem really? Do you not use dns for network naming? Maybe you have to manage the hosts file on every client then. -

High CPU usage on sites with flash content
I have a 2.8GHz, 2GB RAM, Windows XP Pro SP2 machine.
When I visit sites with alot of flash content with Firefox 3
or IE or Chrome my CPU goes to 80-90% and stays there.
I uninstalled flash player and reinstalled the latest
version, but with no fix to the problem. Don't seem to have any
virus/spyware on my system.
Uninstalling Flash player on each of the different browsers
seems to fix the problem - visiting the same sites, I don't get
huge CPU usage.
Any ideas what underlying thing might be causing excessive
CPU usage in all my browsers when visiting flash sites?To make clarifications for my previous post (some people emailed me saying that the link says nothing about cpu hogging or excessive cpu usage), you may not visit the LINK previously provided and instead follow the steps given below.
I would also like to point out my kind of problem that these steps successfully solved. The problem was this:
The first time I start up a browser (IE, FF, Opera, or Chrome) and visits a website with flash player files running on it, the performance of my
computer is smooth and fast for the first 2 or 3 minutes. But afterwards, the CPU usage meter just suddenly shoots up from below 10% to a shocking
100%! And there was not other program opened, except the browser; and I was only visiting one website ( e.g., Youtube).
It then clearly indicates that flash player is the culprit, since I have already run windows updating, spyware and antivirus scanning, defragmenting,
browser cookies and cache clearing, junk cleaning, and drive checking. I have also tried uninstalling and reinstalling flash players, which was actually
a good thing except that during that time I have not yet known about the next 4 steps (given below).
If you have the same problem, you might try th following:
NOTE: Close your browsers and any other running programs and opened windows first.
STEP 1: Navigate your way to this folder: Computer > C: Drive > Windows > System32 > Macromed > Flash
STEP 2: Right-click over the file ‘Flash10a.ocx’ and choose ‘PROPERTIES’.
STEP 3: In PROPERTIES, choose the ’SECURITY’ tab > Click on the ‘EVERYONE’ account or your own Windows account profile, and the button called 'EDIT’ and then tick the box called ‘ALLOW FULL CONTROL’ and also choose your own Windows local account name to have full control.
STEP 4: Repeat this process for the file ‘FlashUtil10a’.
Open a browser and check the performance of your CPU.
PS:
The example here indicates that the flash player version is 10; however, you can still use the steps for lower versions. For instance,
if the version of your flash player is 9, look for all files named FlashUtil9a (disregard the extensions).
Also, the Folder Directory is applicable for Vista users. The file directory structure of your drive C:\ may be different if you are using other windows OS version. You just have to search the location of your Flashplayer.

i have two network drive and i am trying to copy a file from my mac mini to one of the network drives, but i keep getting this error message "One or more items can’t be copied because you don’t have permission to read them." i have no idea why this is since i have always been able to copy stuff back and forth. i checked my file sharing permissions and it is set to read and write for admin (me), none for everyone and read for guests. can someone please, this is very annoying and this is the second time it has happened to me.
neither move nor copy is working. both way gives same error message. what i would like to do however is move the file. yes i am logged in as a the admin and the issue is affecting not just that particular file in my system but others as well. i looked at get info and no the file is not locked but under permission, it says everyone and read only. it will not let me change this setting from get info however when i look under system preferences for file sharing, my setting is read and write for admin (me), none for everyone and read for guests.

I have recently had to hand back my work computer having had my email account closed as well. I have opened a new account but having done this I cant open the books I have on my reader that were purchased through my old account. How can I open my books on my e reader now? Please help.
Yes, I guess as the new account I had to open and then reassign my reader
to purchase more reading material as the new account id has I guess blocked
my reading of the previously purchased books already saved. Does this make

Google Earth Plugin and LabVIEW: High CPU usage when adding placemarks
Hi,
I posted this question on stackoverflow earlier this week but feel it might be better suited to the LabVIEW community specifically so I'm reposting here:
I'm writing an application which uses the Google Earth Plugin to display events on the globe. Each event is a single point kml placemark with an icon which is a 3kb png file. Placemarks are uploaded to the plugin as they are received by the software. I am experiencing increasing CPU usage with the number of placemarks that are added.
I have tested displaying a new placemark every second and running until the software running the plugin completely froze (graph attached). The GEPlugin (green trace) stopped responding (i.e. the globe did not respond to the mouse) at around 1200 placemarks added and CPU usage was at ~30%. When the software itself (red trace) froze the plugin was using around 50% CPU and ~3700 placemarks had been added). After the freeze, no new placemarks were added which caused the software to respond (but not the plugin) so I could clear all the placemarks. After the placemarks were cleared from the globe, the CPU usage of the plugin returned to around 5% CPU.
So what I've seen is that GEPlugin CPU usage increases linearly with each kml placemark added. Is this the expected behaviour/ a normal limitation of the plugin? If not is there a more efficient way of adding many placemarks to the globe?
I am using GEPlugin version 7.1.1.1580 (API version 1.010) and LabVIEW 12.0f3
Please see the test results attached. Any input greatly appreciated!

Performance Log 020114_095115.png 82 KBHello,
I have had a look at your graphs and understood what you are trying to do. To me it seems that as the image gets more complex it gets harde to render which wold likely cause increase in CPU usage resulting in the freeze. I would suggest you try running the program on anoher computer to check on the RAM front of things. If this is a limitation of the GE Plugin then unfortunately I can not do much to help, but if you think this is a problem coming from your LabVIEW code then you can post your code here and I can take a look. -
I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.
I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?
I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.
There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.
Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.
The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.
Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.
The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).
I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.
This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.
Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.
I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.
I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.
The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.I share jmward's frustration. This is not a bug report so much as a request for a badly needed feature, ie the ability to have Firefox be able to tell us which tabs on which windows are eating time so we can target them. There are some very poorly written web pages out there which just plain loop while making no updates or inconsequential updates on the page.
This is not a OS problem; jmward runs Windows and I run Linux but we have the same issue. It is not a question of Firefox plugins or extensions, or even viruses; I have a new, clean Linux install but have the same problem on both my regular Firefox AND on a FRESH install of the latest Firefox (35.0.1) which has *NO* non-default plugins or extensions.
Here is an example of a web page which will eat 100% of one CPU's time:
http://patch.com/massachusetts/arlington/arlington-woman-allegedly-attacks-neighbor-snow-blower-0
I will attach 3 images to back up my claim. All of the images show my dark blue system monitor (gkrellm) superimposed on the web page. The top graph shows CPU time. I have 4 CPUs in my machine, so 25% means the web page is eating 100% of one CPU equivalent.
The first image shows the load of the offending page with elevated CPU usage along with the download net activity on eth0, but the CPU activity does not stop when the download activity is over.
The second images show the steady state 100% CPU equivalent of this page just sitting there apparently doing nothing. It IS, however, doing at least two different things. I know from my regular Firefox where I have "Remove It Permanently" installed that if I remove the the little weather indicator in the upper right of the offending page that CPU utilization drops to about 40% of one CPU equivalent. If I use RIP to remove everything else right down to a bare screen that 40% utilization stays until I delete the tab.
The third image shows the CPU utilization drop to zero when I delete the tab holding the offending page.
Now I will add a note here: If the offending page is NOT the top tab in a window then it stops eating time. The offender will also stop eating time if I minimize the window. However if I have another window up but leave the offender up on top in its window it continues to eat time even tho I am looking at another window. The offender will continue to eat time even if its window is completely covered by another window, and it will also eat time if I switch to another desktop.
I will often have half a dozen windows open, and there are many pages out there which will suck endless CPU time. Unless I want to open up a new tab on each window before I leave it there is likely to be some tab on top eating time uselessly. Get a couple of those going and Firefox becomes sluggish and can even stop responding for many seconds.
I guess I not only want to have Firefox tell us which tabs are eating time, but I would also like it if Firefox would stop giving CPU time to any tab which is not visible because it is covered by some other window and/or it is on a desktop which is currently not showing. If you can stop a tab's CPU usage by reason of tab-not-showing then you should also be able to stop its CPU usage when the window is covered or on the not-top desktop. Indeed is there any reason to not schedule absolute CPU utilization priority to the visible tab on the window with focus and give time to the other tabs only when the visible tab isn't using time?
My final thought on this is that I have had Firefox SO tied up sometimes that I swear their are web pages which are eating time even tho they are not the top tab. I regret that I do not have an example to show you. But Firefox grinds to a complete halt on a regular basis, and that is not acceptable. I am a programmer with long experience in multi-threaded programs so I *know* there is no reason you cannot do better. If there were another browser around which had the commitment to privacy which Firefox has I would probably switch out of shear annoyance. :-( -
Dear all,
since we use Flash Builder 4 final release, we observe a very high CPU usage (Vista or windows 7 same behavior. Configs with 4GB or 8GB doesn't change anything ), after 10 to 20 minutes of usage, that suddenly goes to 60-80% for eclipse*32 process. Heap memory fix in eclipse.ini doesn't change anything, even if this problem seems to occur when Eclipse*32 process is above 500MB.
Does anyone observed this ? What can we do ? Starting and relaunching Eclipse is the only way to get around for now.
Regards,
CédricSameer,
Thank you very much for interesting on that issue, that it is really annoying on the day to day development work, as we have to quit eclipse with FB an average of 3 times a day either because it is becoming extremely slow, or because we have an OutOfMemory popup at some point.
It is quite difficult to define what exactly trigger this over CPU usage. However, it seems that it is mainly debugging stage that it is the cause of this, as we just code and build without launching the app, the phenomenon occurs much later.
What we can also observe is that it seems to be linked to memory consumption of eclipse process, as when we exceed a rough 300-400 MB in Windows Taks List generally we also have this 50-70% CPU usage, and only quitting Eclipse solves the issue. But cannot ensure that it is always the case, I mean we can have the CPU usage increase sometimes with 800 MB and sometimes with only 300MB windows memory consumption.
Note then that increasing eclipse memory parameters in eclipse.ini doesn't change anything to this issue, maybe slightly delaying it a little bit, but that's all.
Regarding your other questions : we have many projects in the workspace, but of course we try to avoid having several opened at the same time, because search, refactoring, content assist are much longer if you have many projects opened. We can also say that this phenomenon occurs only with the main project, which is quite big (~300 classes, 40K-50K lines of code).
Unfortunately I cannot share the project as it our main asset and strictly confidential. But what I can say to you, and we think it might be a important point to check, is that project is a multi windowed AIR 2.0 project massively using Flash GoogleMap API, and RemoteObject services with the GraniteDS client server framework. We have observed another issue, but well documented is that memory consumption of the application being running under adl is growing very quickly if we display lot of objects on google maps (400MB-800MB typical memory footprint). But please note that when application is stopped and adl.exe terminates, this memory is freed, our problem here is the eclipse CPU usage process only.

Kernel_task high cpu usage when using external monitor at 1080p

My external display is a Samsung PX2370 connected to my MBP using an HDMI cable with a HDMI-to-miniDP adapter
I first noticed this after the last EFI update several months back. At first I thought kernel_task eats up too much cpu cycles whenever an external display is attached, but it turns out this only happens when the external display is set to 1080p. When external display is set to 720p, kernel_task is pretty much normal (~5% cpu usage) but rises up to ~150% cpu usage once the external display is set to 1080p.
kernel_task cpu usage is also with normal range when my MBP is connected to a Samsung LCD TV at 720p.
Anyone having the same problem or know of any fix/workarounds?Seems like the problem persists when playing a 720p video on the external display set to 720p. To sum it up

IPhoto 09 on Snow Leopard: 100% CPU usage
Any explanation for this high CPU usage?
ThanksStart with the troubleshooting basics:
1. Delete the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
2. Repair Permissions using Disk Utility
3. Create a new account (systempreferences -> accounts) and see if the problem is repeated there. If it is, then a re-install of the app might be indicated. If it's not, then it's likely the app is okay and the problem is something in the main account.

100% CPU usage. RV180W Firmware Version 1.0.2.6
Since I updated to Firmware Version 1.0.2.6 cpu usage shows 100% with no sing of lowering.
So since 2 days now its always runngin at full speeds for no reason.
Firmware Update, Factory Reset, Setup as before. => 100% CPU
Is this a common problem? Is there any fix for that? Or at least a way to get informations what causes this?
Kind reagards

Workflow vs. assignment engine
Is there any advantage of using the assignment engine vs. equivalent workflow rules? I find the workflow more powerful in terms of use of expressions and flexibility.
