Strange CPU Usage
Hi. Task Manager is reporting my CPU usage at 50-100% all the time. System Idle Process is in the 90's. This doesn't make sense to me. I can't figure what program is using up my cpu!
As far as I know, any process that is using your cpu as you describe will appear under "processes" - there is no way for anything to "hide" itself.
Try ordering the list by cpu usage and keep an eye on the top 4 or 5. Why download something that task manager does anyway?
I also suggest you might have better luck "doing a google" - this doesn't sound like an msi problem!

Anormal cpu usage with kernel 2.6.17
Hi,
After upgrading my kernel, i noticed a strange cpu usage.
Outpout of top :
top - 13:34:40 up 34 min, 3 users, load average: 0.00, 0.00, 0.01
Tasks: 85 total, 1 running, 83 sleeping, 1 stopped, 0 zombie
Cpu(s): 0.0%us, 0.3%sy, 0.0%ni, 87.7%id, 0.0%wa, 0.3%hi, 11.6%si, 0.0%st
why 11.6 %si, i nerver see that before the last upgrade.
Thanks for your help.

Does this make any noticeable difference to your PC's performance?
Just curious.
For me, yes. As I said in the bug report, my computer is very laggy when the problem exists. I can't stand using it.
At the moment, I am using custom compiled versions of the 2.6.16 kernel (2.6.16.27, will update to .28 today) and the latest NVIDIA drivers. With this configuration, everything is fine.
There is the same behaviour with or without nvidia driver.
Bummer. I guess our problems are different. I experience the slowdown only when using X with the NVIDIA drivers. When X is not running, or I am using the "nv" driver, the problem does not occur.

Stripchart control, strange high CPU usage
Hi all...
I have tracked a strange problem with stripchart control.
I noticed in the past that "sometime" different programs I wrote had an abnormal CPU usage, not justified by any activity they were actually performing.
Finally I had the time to track down the problem and to build a minimal sample code.
The presented program has a panel with a stripchart control and two command buttons.
The buttons simply clear the stripchart and add a single point to the empty stripchart.
int CVICALLBACK ControlCB (int panel, int control, int event,void *callbackData, int eventData1, int eventData2)
switch (event) {
case EVENT_COMMIT:
switch(control) {
case PANEL_BUG:
ClearStripChart(panel,PANEL_GRAPH);
PlotStripChartPoint (panel, PANEL_GRAPH, MAGIC_VALUE);
break;
case PANEL_NOBUG:
ClearStripChart(panel,PANEL_GRAPH);
PlotStripChartPoint (panel, PANEL_GRAPH, NOT_SO_MAGIC_VALUE);
break;
break;
return 0;
I found that adding "special" values to the stripchart starts a background activity that consumes a significant amount of CPU time.
In this screenshot you can see what happens on my PC when I click the "Bug" command button.
The special value is here 42.22 but I bet there are other thousands with similar behaviour.
Being a single point, the stripchart does not show nothing but the change of the Y axis scale.
Clicking the "No Bug" command button inserts the value 100.0 and no bad behaviour occurs.
Just to shuffle ideas, if you push "No Bug" and then "Bug", the bad behavior does not occurs, too.
It's surely an interaction between the Y axis autoscale, the initial values and may be the "scale name". I haven't the time to explore all the combinations and may be a minimal workaround.
In my applications I ended in doing the autoscaling "by hand".
I have tested the program on five different PCs, Core 2 Duo CPUs running XP, Vista and 7 (italian), compiled with CVI 2010 SP1
Attached there is the full project.

StripChartCPUeater.zip 5 KBThere was a bug in the graph/strip chart code which could cause endless cycling when attempting to resize a graph axis which had an axis label visible. It has been fixed for the next version of CVI so unfortunately you're going to have to wait a little bit.
There are two possible workarounds:
1) disable the axis label. If it isn't displayed, this looping can never occur.
2) Enable Fixed plot area and play around with the left and width of the plot area to move the whole thing over to the right a bit more. The problem was introduced when the graph/chart thinks the label is getting too close to the edge of the graph and attempts to reposition the label. Unfortunately the code was a little buggy and the label was getting positioned in the exact same spot, but we weren't checking to see if we'd already tried to reposition the label, and so it endlessly cycled.
Sorry about the inconvenience.

I've been having some odd behaviour with combo box behaviour in LV8.2. When the mouse is hovering over the combo box and the down key on the keyboard is pressed, the CPU usage goes to 100%. Moving the mouse off of the combo box causes the CPU usage to drop.
Does anyone have any insight as to why this is happening or, hopefully, how this can be fixed?
thanks,
bryan

oh, i've tried this on two PCs as well, one with dual cores. One the dual core machine one of the cores goes to 100% (giving a total usage of 50% as ravens fan noticed). One the single core the CPU goes to 100%
Actually what was kind of odd about mine was that the usage was 50%, but the 2 windows showing each core seemed to mirror each other and were both showing about 50% as well. Not sure what that means. -
SBS 2011 - High CPU usage - Help me Microsoft forums! You're my only hope!
My company supports a client that has a SBS 2011 server. For about the past year, we've been fighting a recurring issue with performance on this server. There are about ten local users and four remote users. The server's CPU idles at
about 60%-80% but is usally running when under *any* load from 80%-100%. If you do anything on the console, it will stay pretty much at 100%. These are not power users by any means. The server is utilized for file/printer sharing, Exchange
2010, and one flat file database application (non-SQL). SharePoint is not utilized.
Needless to say, our client is frustrated. When opening files, using their database application, or doing anything Exchange-related, there is a large amount of lag on the client side. First, here are the server's specs:
Make:Dell PowerEdge T420
OS: SBS 2011 Standard SP1
CPU: 2 - Intel Xeon E5-2407
Memory: 32GB
RAID: RAID 1 - Operating System (C:)/Data Volume (E:) | RAID 5 - Data Volume (D:)
Here is what we have tried to resolve this to finality:
* Doubled resources - Initially the server had a single physical processor and 16GB of memory. While these specs alone should have been fine, and were fine when the server was installed, we had periods of time where the server would just sit all day at
100% usage. We doubled the resources and while this seemed like it would fix the issue, we are still seeing abnormally high processor usage.
* Removed all monitoring tools, antivirus, and backup software - As part of our testing, we removed our monitoring agent (LabTech) and antivirus (GFI Vipre). Mozy is utilized for an off-site backup so that was disabled. No dice.
* Verified updates - We made absolutely sure the server was 100% patched.
* Malware/Virus/Rootkit checks - We have ran scans checking for any potential issues with security.
* Ran MBSA and MBCA to fix any issues with the server's configuration.
There is no single process which is using all of the CPU, or we would simply be able to narrow it down. Our calls to Microsoft support have yielded no answers. The last call ended with Microsoft stating that a SBS server should always be running
at high CPU usage. Meanwhile, we have many other clients with less-beefy servers, with more users, who have no issues like these.
So, I'm turning to you all. I will gladly provide logs, configuration settings, even remote assistance sessions if you all can help shed some light on what might be causing my issues.
Thank you!Some comments/ideas:
How long was the server running after this screenshot? I ask because store.exe is only got a 1GB of RAM which is really low - it should grab most of the RAM within a few hours.
The server was up for about 12 hours. I believe an adjustment was made before to limit the Exchange memory usage.
Strange that SearchIndexer (wsearch service) is so high although that may be a startup condition.
The LT* processes seem to be a 3rd party monitoring tool - no idea why it would ever need that much CPU though (I thought you disabled this?).
We had, but we cannot go forever without monitoring our client's server. It has been pulled off in the past and results on performance are pretty much the same.
The taskmgr process run by amnet_admin has used a lot of total CPU Time. What is it? (can't see the command line).
That's the user I was logged in as when I took the screenshot. Even the task manager seems to eat up the CPU.
The sqlserver process right above it is also busy - may want to look at the command line and figure out which SQL database that is (SBS has 3 - WSUS, Sharepoint, and SBS monitoring)
I believe that's the SharePoint database. They don't currently use their site. Would you recommend a removal and reinstallation? I would not completely remove as I know SBS doesn't like you removing parts of the complete package.
Strange that vds.exe is 10% - that is the interface to the disk management interface IIRC. Perhaps your monitoring service has gone awry here - definitely lose it.
I'll see about pulling it off and I'll see if there are any improvements.

Hi everyone,
I'm having an issue with Word 2013 and I'm hoping someone can help. Seen as I got fleeced for my TechNet subscription this year (the price given on the invoice doubled when I called up to pay!) I’d very much like to see a speedy fix from the Microsofties
please! :D
Recently, I've found that Word will consistently exhibit high CPU utilisation, ~50% on a dual core second generation Core i5.
This continues, even when I’m not providing any input to or interacting with the Word window and even when the Word window is covered by other windows. Minimising Word causes its CPU usage to drop back down to zero.
The strange thing is that, so far, I’ve only observed this with a single document. I started writing this document at the start of this week and it’s been authored exclusively on Word 2013. In fact I’m the only one who’s editing it and I’ve only used a single
computer (and this one single install of Word 2013) to do so…
There’s nothing particularly unusual about this document, and a different but similar document which uses the same themes and features (in fact the theme for the second document was created from the first one) doesn’t appear to cause the same issues. Both
these documents are stored on SkyDrive, and are being edited directly from there.
Initially I tried the much recommended tweaks of disabling hardware graphics acceleration and sub-pixel positioning, however neither of these has had any effect.
I investigated a bit further using Sysinternals Process Monitor, and found that while Word is using a lot of CPU it’s actually looping very, very quickly polling for the existence of the registry key “HKCU\Software\Microsoft\Avalon.Graphics”.
This key doesn’t exist on my system, and a quick test I conducted where I created it just lead to Word looping polling for more non-existent registry keys.
My system is a HP Folio 13 running Windows 8 Pro x64 with Office 2013 (RTM, not Beta) 32 bit. Both Windows and Office are fully patched, as is everything else on the system.
Thanks in advance for any help anyone can offer.
ChrisHello again,
After working on my problematic document some more, I believe I’ve found the cause of the issue.
@Microsofties – I think this one is either a bug or a dodgy OOTB template…
I noticed that the high CPU usage only seemed to occur when the document’s footer was displayed. Experimenting with some careful scrolling and zooming to hide footer (without actually using the “hide white-space” option) seemed to confirm this so I investigated
the footer a bit more.
My document was using the standard Word “Facet (Odd Page)” footer template with a couple of fields added to suit my needs, namely “Publish Date” and a page number.
The template seems to be structured such that the content of the footer is inside two nested text boxes (one inside the other). I also noticed previously that this footer template also appears to “jump” up each page and back down again as I scrolled.
So I deleted the footer and its text boxes, and recreated the same content, in the same position (using the standard paragraph alignment tools) by hand without the nested text boxes. This has, so far, fixed the issue!
I also noticed that the CPU usage dropped right down to idle the moment I deleted the nested text boxes.
Altogether, this leads me to conclude that the “Facet (Odd Page)” footer template in Word 2013 is the source of my issue. Specifically, I believe that the use of nested text boxes in this template causes Word’s interactions with the .Net 4.5 WPF to go a
bit nuts, as evidenced by the infinite loop of request for the non-existent “Avalon.Graphics” WPF registry key I mentioned previously.
It would be nice to see some feedback on this one, Microsoft people, if only to know if this is actually a general issue or is specific to my document!
Thanks, Chris -
Sometimes, after a while, firefox (36.0.4) uses up 1 core of my CPU (is a quad core due to hypertreading). The way it happens is really strange. Many tabs without a problem until suddenly ff decides to floor it. This is alway in the run, not on startup or close. All add-ons need to ask my permissions to be activated, this includes flash.
On close, I ordered ff to clear all history and cookies.
Notes that could be important (The behavior encountered while using it. This varies from time to time):
opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
==> The above makes sense
- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript
==> The above seems odd
- Browser is idle in the background (not actively using it). Then all of the sudden "lets floor it until closed".
==> The above seems pretty odd
- When confronted with high CPU usage, closing ff doesn't close it (the ff process remains active. Not a ff process, THE ff process). => High CPU usage remains
==> The above looks like that there is definitely something wrong here
This last one has some other things to keep in mind
- When it happens and I close ff, upon restarting it it will ALWAYS ask to close ff. After confirming to close it, it will start and behave normally.
- When killing ff via the task-manager, or other means like powershell commands, restarting it will result in an idle ff even after every tab is loaded again.
I hope this isn't a heisenbug and there is a solution to this, a reboot ff button would be a nice workaround though. I personally think that it must be some routine in the code that decides to go nuts for no reason.
If you need further details, feel free to ask.
Thanks in advanceTried those before and tried them again. Unfortunately, the problem keeps repeating itself at random times. As said, sometimes it doesn't occur and sometimes suddenly it does. Keep the following things in mind about this, what seems like a heisenbug, behavior.
- opening new tabs (a lot or a few) => "heavy" load during site loading, then idling

- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript

==> The above looks like that there is definitely something wrong here
As stated, a reboot ff button would be a nice workaround. I personally think that something like a tread must get stuck in some sort of infinite loop. Browsing in ff works just fine though. I just don't like the fact that I turns into a "gasoline guzzler".
Again, thanks in advance -
High CPU usage while display is asleep
This is a strange one, and I've noticed it on multiple distros, and Arch is no different. When my system is sitting idle with the screen on my CPU usage hovers around 5%, which I would consider to be perfectly normal. However, when the display goes to sleep (no screen saver, just DPMS sleep) the CPU jumps up to about 25% and stays there until I bump the mouse (or do whatever to wake the system up), and then it will drop back down to the normal 5% CPU usage.
I had always thought it had something to do with Firefox, but I had Firefox closed while I was away at work today, and yet when I come home and wake my computer up my CPU usage graph shows that it's been at a solid 25% all day long.
Anyone have any ideas what this might be, or recommend a way to hunt down exactly what process is eating my CPU cycles while the display is off?
Thanks a lot, this has been puzzling me for some time now.
EDIT: I should add that I am running KDE, and have been on the other distros as well (to the best of my recollection). After realizing this it seems like this thread may be better suited for the Applications & DE forum, but I'm not sure... it could very well be something to do with the kernel or something to do with power saving. Please move if you see fit.
Last edited by hippieben (2014-09-07 00:17:46)The CPU usage is not accounted for in the system monitor app. There's roughly 4% usage accounted for, yet there's a total of 29% being used.
The script doesn't seem to find anything either. High idle CPU usage kicks in maybe 3/4 of the way through, but the output doesn't seem to change from the beginning at all.

Also, the screen doesn't have to be asleep, the system just needs to sit idle for a few minutes.

How can I identify the cause of high CPU usage
Just recently, my Mac Book Pro CPU usage has gone through the roof, and the temperature quickly rises to around 80ºC, with the fans are working pretty hard to keep it there.
I've looked in Activity Monitor, but there's nothing unusual as far as I can tell in the list of processes, but it does show that the system is continually using between 30% and 40% of the CPU all the time, even if I have no applications running. From a cold start, it starts using that much CPU as soon as OSX loads.
Here's a screen grab of the activity monitor window
One thing I thought was strange is the amount of Virtual Memory that Growl uses (37gb) but according to the growl website, that's not unusual. I've also tried quitting Growl, but it makes no difference.
I have 30GB of free space left on my HD.
Any ideas? I'm worried my Mac Book might be on it's last legs, so I'm hoping and praying that this is something simple-ish.
thanks

And now a strange case...
Installed 10.9.4 but it became unusable because of excessive CPU usage. Reverted back to 10.9.3 but now the problem persists!
Basically, if connect the Ethernet cable the CPU increases and temp raises from 45C to 95C. As soon as I remove the Ethernet cable and stay on WiFi things go back to normal. I already have done the most obvious, i.e. reinstalling the OS from time machine, removing launch daemons and plug-ins, and fixing disk permissions. Check the details below. Any idea? It would be much appreciated. I'm getting nuts with this.

This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2. -
Hi everyone,
I used to have my own kernel running and everything was fine.
Recently, after the cool changes which happend with kernel/udev related stuff in the last months and weeks, and with the "beyond" kernel being available and having the possibility to use software suspend2 an easy way, I thought it would perhaps be better to switch to the beyond kernel package, staying up to date easily and not having to care about wether some update perhaps wouldn't work with my old kernel anymore...
After some minor hassle, I got it working fine and thought, well, runs reasonably well. But then I discovered some strange issues:
* If I boot with the regular kernel, log in to the console, use mplayer to play an mp3/ogg file, I got 22% cpu usage by mplayer, and additional system cpu usage, summing up to only 66% of my cpu is in idle state!
* If I do the same thing with the beyond kernel, it is still around 7 to 8 %, the CPU has a maximum of 87% idle time
* If I start up X and start xmms, without playing anything, even with stock configuration and nothing changed/enabled, xmms will take 12% of my CPU!
* If I run some other things aside (like mplayer), xmms - still being idle! - still uses 4% CPU
* if I actually use xmms, it takes up to 20% cpu
* now mplayer only uses 2% CPU - but still too much for only playing a music file
So I just don't have anything left than scratching my head. What's going on there?
Ford PrefectXMMS doesn't play nice with today's Linux scheduler. It's old. (I still use XMMS -- out of sheer habit -- and ignore the problem.)

CPU usage is 98% when running my exe labview program
Hi
I have made an executable and installer for my labview program. When I install and run, the program uses a lot of cpu - almost 100%, even when the program is not computing. I recently changed over to LVIEW 8.2 from LVIEW 7.1. I had none of these issues with 7.1.
Programatically, I use a state machine to continuously execute the program. I also use a couple of while loops as slaves to plot the results processed in the main loop. In all while loops I have a 'Wait' until next ms' vi to prevent the program using all the cpu, but it doesnt seem to be helping in LVIEW 8.2. This is somewhat strange.
Can someone suggest what may be happening? and are there any methods that I can use to reduce cpu usage of my program?
Cheers
RVRIt will be impossible to really troubleshoot this without a lot of additional infomation.
Is the CPU usage only high in the built application, or is it also high if you run the same program in the 8.2 development environment?
Was the 7.1 program exactly the same, or did you make any modifications since?
Are you running 8.20 or did you upgrade to 8.2.1?
What does the program actually do? Does it interact with DAQ hardware? File I/O?
What does the program do when it is "computing"? Is the CPU use even higher then?
Is there also a wait statement in the main while loop?
What is your OS (windows, linux, mac, etc.)
Is your computer reasonable for the task. Enough RAM, etc.
How do the various loops communicate with each other? (queues, local-, global-, shared- variables, etc.)
How much data is exchanged between the loops? At what rate?
Do you use fixed or variable size arrays?
Can you give us a more detailed overview of the code?
How is the memory usage?
have you done any profiling?

Evenlog viewing causes CPU usage 100% on Windows server 2008 SP2
We have Windows server 2008 SP2 with strange behaviour. When I scroll down events in eventlog viewer CPU usage hits 100% and eventlog viewer freeze. CPU usage is split between 2 processes SVCHOST.EXE (lmhosts, eventlog and Dhcp services) and MMC.EXE.
1)I tried to replace eventlog files with new ones. That didn’t helped
2)After server clean boot problem still exist.
3)When CPU hits 100% usage process explorer shows that from SVCHOST.EXE process CPU is used by service EventLog.
Any ideas how to fix this?Hi Santosh
I re-installed VMware
tools and also configured VMXNET 3 - nothing changed :(
Sorry to hear that.
Windows event log service has couple of dependencies i.e. task scheduler and windows event collector service. Can try restrating those services ?
In addition to above, try following steps
Change NTFS permission of %WINDIR%\System32\WinEvt\Logs directory, add Local Service and
Network Service, give them FULL permissions.
Stop and Start event viewer service by running following command
net stop eventlog && net start eventlog
Issues like this might occur if the disk (FC or iSCSI SAN or even NAS) has some inconsistencies , this is true in case of both physical and virtual machines
You might want to try running chkdisk as well on the server in question

Why CPU Usage showing spiky line when Demand showing a smooth line?
I always thought that CPU Demand should be identical with CPU Usage, because both are average. So the chart below comes as a surprise to me. This is from vCenter 5.5 Update 1. There is no contention, as can be seen from the Entitlement counter.
The values are actually the same. The Demand line is somehow an average of the Usage. When both values are rolled up to 5 minutes, they become identical. The data at vCenter Operations shows that.
Question: why is the line pattern so different? The Usage showing a spiky line while Demand shows a smooth line. The Demand line makes sense as it is an average of 20 seconds. The Usage is a bit strange as it fluctuates drastically.
Thank you
e1I had a discussion with a friend on this. The 2 counters are both average, and are tracking the same thing. One of them has to be the "wrong" one. We think the CPU Usage pattern is the misleading one, because each sample is 20 seconds. That is 20,000,000,000 nano seconds. There are also 2 low point for 1 high point. It is strange for a CPU to be low for 40 billions nano seconds, then spike for 20 billion nano seconds.
The chart is from vCenter 5.5 Update 1. The host is ESXi 5.5

Hallo,
I have a strange problem with my applet. It displays medical images. After loading Image the CPU usage of java jiumps to 100% on single core processors and to 50% on 2 core processors, and stays high, without any interaction of user. I've used Java VisualVM to profile the applet and it says that: javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run() 94.76343 787851 ms (94,8%) 58823 times invoked is
I'm not sure this is the cause of the problem. I don't use any loops while noone is interacting with the applet. Has anyone idea or suggestion what's going wrong?
This CPU load is independent of browser and operating system. I've profiled it on firefox.
with regards
Rafal ZiolkowskiGood job figuring it out.
Rule of thumb to prevent future problems: the paintComponent is used for painting and should do nothing else - setBorder() is a state change and thus does not belong in the paintComponent() method. You can all relate it back to a general programming rule of thumb: a function or method should perform only one task.
