Some process cpu usage too much!!

I have many problem when update Mountain Lion.
some process are too much usage cpu .
iMac Processor : 3.4GHz Intel Core i7
Ram : 16GB 1333 MHz DDR3
Problem Process:
- safari web content.
- image capture extension.
- mdworker
There are usage too much cpu , so iMac too slow!!!
Please solve it .

I have the same problem here, my MacBook Air barely goes to 60ºC while doing normal tasks, but as I edit video in iMovie (or even just letting iMovie open without doing anything) is gets near 100ºC because my CPU load is always very high!
Can someone explain this?

CCM process cpu usage

Hello!
We have 2 CCM subscribers. Their configuration, registered devices are nearly the same. (1300 and 1500 phones, 80, 90 h323 gateways). Node 1 cpu usage is 20%, while the others is always between 80-100%.
What can such a big difference?
(when I moved more than 400 phones and 1 vgw with 2 E1 lines, nothing changed!)
Thanks,
Bela

Hello!
MCS-7800 Intel Xeon 3.06 Ghz, 4G RAM
4.1(3)sr2
MGCP gateways (4 E1) is registered to the 20% node.
H323 gateways is nearly equaly registered to the two subscribers. (I mean their DP ccmgroup setting).
1 more interesting detail: the 20% node handles twice as many calls as the 90%.
Thanks,

System CPU usage too high

Hi, i've been trying to troubleshoot this problem for some months.. everytime i try to use perfmon or another program to watch for network usage (download and upload) the System process spikes to 13%~ constantly until i close it.. I could "live"
without that but now everytime i'm using an application on my second monitor, the same thing happens... started happening just an hour ago, and it's really bothering me because i don't have a clue what driver could possibly cause this.
I've tried capturing xperf traces on another forum but they keep come as corrupted as the person whose trying to troubleshoot with me tells me, and i can't seem to get a grip of the xperf analyser myself to see what (driver?) is using the cpu so i can try
to replace it...
Anyway, as i type this it jumped up to 20% and i don't know what to do.
I'll upload two xperf traces here, but at least one is "corrupted" as the other kind member on the other forums told me. (which is the first one below)
https://dl.dropboxusercontent.com/u/36066558/highCPUUsage.7z
https://dl.dropboxusercontent.com/u/36066558/highCPUUsage2.7z
And the one i just recorded, https://dl.dropboxusercontent.com/u/36066558/highCPUUsage3.7z
Does someone have another way or can help me find what's causing it?
I used the command xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 512 -FileMode Circular && timeout -1 && xperf -d highCPUUsage.etl
I took a print of the System process Threads in Process Explorer http://i.imgur.com/vbW36rU.png
Before the today's change, the function shown there was mostly ntoskml.exe!KeGetCurrentProcessorNumberEx+0x34, i don't know if that means anything...
Thanks.

First Xperf has been replaced by Windows performance recorder. Second there was almost no data recorded in your trace. Please run a windows performance trace as instructed in the wiki and upload it. Make sure you run the trace when the
problem is happening
In order to diagnose your problem we need to run Windows performance toolkit the instructions for which can be found in
this wiki
If you have any questions feel free to ask
Please run the trace when you are experiencing the problem

Dtraced process CPU usage * 5

Hi,
I have a process of which I want to trace the libc mutex
lock/unlock activity. It takes 3,5 % CPU, when dtraced
it takes 18%. I thought dtrace's impact was minimal?
Stoping dtrace brings it back to 3,5.

Dtrace's effect is minimal when it's not doing anything.
Dtrace's effect when it is doing something is proportional to what it's doing. If you ask it to activate a few probes that aren't hit much, it takes very little CPU. If you ask it to activate probes that fire thousands of times a second, it's going to take a lot of CPU.
The cool thing about dtrace isn't that it's free when it's working, it's that it's free when it isn't working. That hasn't been true for many other tracing technologies.

MBP with 10.6.8: CPU usage high, no responsible processes shown in Activity Monitor. What causes this?

After using my computer for some time, CPU usage climbs to about 90% (ca. 65% user / 26% system) and fans run at high speed, but there is no processes that seem to use CPU (other than Activity Monitor itself ~1%).
This has happened a few times recently. It happens when I've used my computer for some time, hours or a couple of days (I usually put my computer to sleep when not using it but rarely shut it down). I've tried to quit all running apps incl. Growl, Dropbox, and anything that could be responsible to this but with no results. Putting computer to sleep for a long time doesn't help, cpu usage will climb instantly after wake up. Restarting system is the only thing that helps.
Most of the time I use my laptop with external monitor, lid closed and connected to power supply. When experiencing this, opening the lid causes fans to slow down, but CPU usage remains high and battery drains quick.
Any ideas what might cause this?
My MBP is 15" model with Core 2 Duo 2,66 GHz (MacBookPro 5,3), OS X version is 10.6.8, all available updates are installed.

Perform a SMU reset.

Remove the anti-virus, it's running a root level process all the time that's taking your CPU and it's not necessary as there are no Mac viruses, Apple has the trojan angle covered already.
Always on anti-virus on a Mac is always a source of problems, also is MacKeeper, uninstall that here if you have it.

If you need to clean the Windows filth off PC files, then use the free, run as you need, ClamXav.

It seems your machine is used in a corporate enviroment, thus likely a rule that anti-virus must be used, you can avoid high CPU usuage by using the ClamXav instead.

Thunar-vfs-pixbuf-thumbnailer-1 using too much CPU

thunar-vfs-pixbuf-thumbnailer-1 process is using too much CPU, noticeably slowing my system...

what should I do?

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

Why it is taking too much time to kill the process?

Hi All,
Today,one of my user ran the calc script and the process is taking too much time, then i kill the process. I am wondering about one thing here even it is taking too long to kill the process, generally it will not take more than 2 sec. I did this through EAS.
After that I ran Maxl statement
alter system kill request 552599515;
there is no use at all.
Please reply if you have any solutions to kill this process.
Thanks in advance.
Ram.

Hi Ram,
1. Firstly, How much time does your calculation scripts normally run.
2. While it was running, you can go to the logs and monitor where exactly the script is taking time .
3. Sometimes, it does take time to cancel a transaction ( as it might be in between).
4. Maxl is always good to kill ,as you did . It should be succesful . Check the logs what it says ,and also the "sessions" which might say "terminating" and finish it off.
5. If nothing works ,and in the worst case scenarion , if its taking time without doing anything. Then log off all the users and stop the databas and start it .
6. Do log off all the users, so that you dont corrupt any filter related sec file.
Be very careful , if its production ( and I assume you have latest backups)

100% CPU Usage caused by HMI

Hi everybody:
I'm working with LabVIEW DSC 8.2.1 in a system that monitors many variables of a plant, such a typical SCADA system. For this reason, the use of the graphic tools is highly used on the development of this system. Everything works fine, but I have only one problem.... the usage of the CPU.
When I am working on the development system I (not the executable) I start the application and after the variables are initialized and every process has started and are running , the CPU usage is raised around 90 - 100%. After a few days investigating the reason of this, I realized thay when I change the view on the screen to another view, for example the block diagram of the application, while the application is still running, the CPU usage goes around 15 - 25%. I've tried these many times changing the view from Front panel to Block Diagram and viceversa and the result is always the same: Front Panel= around 100%; Block diagram or another view (other applications MMIs, or Block Diagrams, etc.)= around 20%.
Another thing that I realized is that the other view (different to front panel) has to fill the entire screen to work the way I'm telling before.
When I build and run the executable, the usage of the CPU is the same... (around 100%), but I can't see any other application, because the application built is the shell of the OS, so no other views are available.
I don't know if there's some other consideration to take into account about the HMI when creating an application, and I'll appreciate very much your help.
Thanks in advance!

100 Percent CPU Usage when you run programs after you install Windows XP Service Pack 2
CPU Usage 100% Symptoms
When you run some programs, the CPU Usage meter in Task Manager may indicate CPU Usage 100%. When CPU utilization reaches 100 percent, programs will run very slowly or stop responding (hang) and your computer is freezing or crashing.
Noteress CTRL+ALT+DEL to view CPU utilization, click Task Manager, and then click the Performance tab.
These symptoms occur after you install Microsoft Windows XP Service Pack 2 (SP2).
CPU Usage 100% Cause
These problem occurs because of the user interface code that is included in Windows XP SP2. The high CPU utilization is caused by the additional overhead that occurs when the IsWindow function is called by the user interface code.

if you still do not know how to Fix CPU Usage 100%?
I suggest you try targeted software - registry cleaner to fix cpu usage 100%
Because there are many cases causing high cpu utilization.
1. If you do a lot of web surfing and are concerned about spyware, adware infecting your machine, they will cause system crashes and CPU utilization reaches 100 percent. Some good registry cleaner has the function of spyware & adware removal.
2. You install many beta version of the software, Drivers are not certified, which resulted in many errors, you get high cpu usage.
3.100% CPU Usage while you use Internet Explorer
4. many unneed Startup Program.
5.Others PC Errors. - DLL errors, runtime errors, Windows-Installer Errors, Windows Startup Errors,paths Broken DLLs, OCX, and ActiveX Components all will cause 100% cpu usage. Your PC will run very slowly.

High CPU usage during 15 acquiring analog input and write to file (suggestion needed)

Helllo everybody,
I have a problem about the usage of CPU now i am using a realtime target (PXI-8186) with Daq (PXI-6259) to get 15 analog signals at the rate of 10kHz
at first i try to get signal at different rate but i found out that all of the channels share the same clock so i get the highest frequency that i desired after that i do
some data manipulation with displaying charts and use shift register to stack data in array of string finally i write the data to spreadsheet every 5 second, by doing this the CPU usage
is always 100% and reduce by the time the file is recordedto 71% or so and then start to increase to 100% again. I think the things that make CPU usage too high are
1. Time loop: because i set the period to be 10ms maybe this is too low.
2. The shift registered: may be it use too much overhead memory but i do not know other method to stack data before writing to a file
3. RAM too low: The RAM of PXI is only 256mb
4. Poor program arrangement: Because i am new to labview the program is not arranging correctly or i may use some inappropriate structure.
My program is very messy sorry about it because i avoid using SubVI and i am new to labview. Please help any suggestion is apperciated. Thanks in advance.
Best regard

It looks like you are writing your data to disk every so often. For that reason, I recommend making it based on the number of samples you have instead of the time. With that you can preallocate your arrays with constants going into the shift registers. You then use Replace Array Subset to update your arrays. When you write to the file, make sure you go back to overwriting the beginning of your array. This will greatly reduce the amount of time you spend reallocating memory and will reduce your memory usage.

Hi Gurjar,
r u getting the below mentioned syslog messages?

106023, 106100, 106004
TCP Out-of-Order packet buffer full (tcp-buffer-full) 1949
TCP Out-of-Order packet buffer full:
This counter is incremented and the packet is dropped when appliance receives an
out-of-order TCP packet on a connection and there is no buffer space to store this packet.
Typically TCP packets are put into order on connections that are inspected by the
appliance or when packets are sent to SSM for inspection. There is a default queue size
and when packets in excess of this default queue size are received they will be dropped.
Recommendations:
On ASA platforms the queue size could be increased using queue-limit configuration
under tcp-map.
Similarly you need to check many reasons for the asp drop logs that you have captured and you need to monitor how much it is increasing and the difference.......
but 40 % CPU utilization is a okay kind of thing and you do not need to worry if that happens only during peak hours ans it is not increasing drastically more and more.

SQL Server 2012 - RESOURCE MONITOR / PREEMPTIVE_XE_CALLBACKEXECUTE high CPU usage

Hello,
We are currently in the process of migrating an existing clustered SQL Server 2008 R2 instance over to a clustered SQL Server 2012 instance as we phase out the Windows Server 2008 with SQL Server 2008 R2.
The setup is identical for the SQL Server 2012 instance as it is on the SQL Server 2008 R2 instance. (meaning the RAM and CPU are both the same or better on the SQL Server 2012 instance)
The process in which we are migrating is that we're moving a few databases over to the new SQL Server 2012 instance each night. What we've noticed is that the CPU usage is much higher on the SQL Server 2012 instance than on the previous
SQL Server 2008 R2 instance even though the there is only 1/2 of the databases migrated to the 2012 instance.
Running the following script:
;with cte ([totalCPU]) as (select sum(cpu) from master.dbo.sysprocesses)
select
tblSysprocess.spid
, tblSysprocess.cpu
, CONVERT(BIGINT,(tblSysprocess.cpu * CONVERT(BIGINT,100))) / CONVERT(BIGINT, cte.totalCPU) as [percentileCPU]
, tblSysprocess.physical_io
, tblSysprocess.memusage
, tblSysprocess.cmd
, tblSysProcess.lastwaittype
from master.dbo.sysprocesses tblSysprocess
cross apply cte
order by tblSysprocess.cpu desc
Produces the following results:
In a clustered environment, is this normal and if not, does anyone know what this means or how to reduce the CPU usage?
Thanks.

Hello,
The following query may help us identify extended events or audit configurations running on that SQL Server server that are producing that high CPU usage scenario.
SELECT
s.name
AS 'Sessions'
FROM
sys.server_event_sessions
AS s
WHERE
s.name
<> 'system_health'
and s.name
<> 'AlwaysOn_health';

Firefox uses too much memory

I've been using Firefox as the default browser on my systems (both Windows and Linux and in 32 or 64 editions) and for some reason Firefox consumes too much memory. Now trust me. I have a very fast machine and so I get very frustrated with this issue as it seems to be a Firefox only issue. Its true that I might have up to 40 tabs open at times but Chrome can handle it Safari can handle it and even Explorer can handle it. Sometimes Firefox's memory consumption peaks to an astonish 3GB of memory which is unheard of. My machine is so fast that I can have up to 10 programs open (Maya, Photoshop, Cinema 4d, Autodesk Suites MySql server and PHP5, MS Office) and still be able to work with them all at the same time, but Firefox crashes suddenly and that is very annoying as I've customized it to my needs adding extensions and making sure all my online baking is done using Firefox. This memory issue is far more noticeable when I'm using Windows 7 64 bits. The same amount of tabs and extensions opened on Linux have no effect on memory and I often switch to Linux just to be able to enjoy a smooth Firefox browsing experience. I've invested so much money into building an amazing machine and it takes 10 minutes of having Firefox running to crash it all completely. I've lost track of the amount of times I've lost my profile and had to rebuild all my customizations but I can stand that. What is beyond my comprehension is the fact that when I'm using Windows XP or Linux the memory used by Firefox is far lower than when I'm using Windows 7 or 8.1 .
Can you help me out? I really love Firefox and would like to keep using it as my default browser but can't afford losing my profile info every time Firefox crashes or having Windows Explorer crashing and losing all the work I'm doing on other software programs.
Much appreciated;
Sam

Are there any tabs reopened from the previous session when this happens?
Do you keep a large history?
You can check for problems with the places.sqlite database file in the Firefox Profile Folder.

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Execution script too much time than before

Hi experts,
We run tunning script on daily basis which analyze multiple table of oracle ebs 11i oracle 10g and we also have execute schema statistics,
Issue is this it take too much time to complete some time more than 12 hrs. It looks like hang on gathereing statistics Inv and ont schema.
Kindly give me solution
e.g
analyze table inv.mtl_transaction_types compute statistics;
analyze table wip.wip_schedule_groups compute statistics;
analyze table WSH.WSH_DELIVERY_DETAILS compute statistics;
exec DBMS_STATS.GATHER_SCHEMA_STATS('APPS'); ---APPS, APPLSYS, INV,ONT,WSH, SYS, SYSTEM, GL,HR,AR,AP,CE,WIP,
---PO,MSC,PJI
exec DBMS_STATS.GATHER_SCHEMA_STATS('APPLSYS');
exec DBMS_STATS.GATHER_SCHEMA_STATS('INV');
exec DBMS_STATS.GATHER_SCHEMA_STATS('ONT');
exec DBMS_STATS.GATHER_SCHEMA_STATS('WSH');
Now its taking more than 15 minut and not yet complete.
Thanks

but to gather statisics for some schema it takes too much time. First it take 3 hrs for whole script now it is taking more than 15 hrs and some scheam go to
complete and some are still hang then we have to cancel this job.
I also experiment to execute one by one schema at that time it is completed normally.Have you done any changes recently (i.e. upgrade, installed new patches, data load ..etc)?
Have you tried to use different parameters? -- Definition of Parameters Used in Gather Schema Statistics Program [ID 556466.1]
You could enable trace and generate the TKPROF file to find out why it takes that long to gather schema statistics.
FAQ: Common Tracing Techniques within the Oracle Applications 11i/R12 [ID 296559.1]
Enabling Concurrent Program Traces [ID 123222.1]
How To Get Level 12 Trace And FND Debug File For Concurrent Programs [ID 726039.1]
I would also suggest you log a SR as "Gather Schema Statistics" is a seeded concurrent program and Oracle Support should be able to help.
