High processor usage using xdm-archlinux

Both xmessage and xclock are running the processor more than needed and continue running after logging in. 
/var/log/xdm.log keeps running var out of disk space with continuous error messages:
Warning: select failed; error code 5

For what I'm using, it is behaving.  I'm not using urxvt.
This may have something to do with the urxvt: https://bbs.archlinux.org/viewtopic.php?id=50963

  • Extremly high CPU Usage using Bootcamp, XP

    I have a MPB 2.5 duo core with 2 Gig RAM and a 8600 Gforce video card.
    Ok so I installed XP Pro. using bootcamp to split my HD. Here is my problem.
    When I first start up windows it has its usual spike of the CPU to around 40% or so. If I open up internet explorer it will run a little high at around 15%. If I open up Pandora that is where the problem starts. With Pandora open it will have a CPU usage of around 30 to 40% and more noticably the audio will speed up and slow down and as you might guess this causes problems with the streaming of the audio. If I run any game or anything graphics intensive it will run at a steady 90 to 100% CPU usage cauing it to lag ang glitch and the fan to be running all the time.
    The weird thing is that on Leopard it will run perfectly. I was thinking the problem may be something to do with the drivers or the hardware.
    Help Please!

    I just started experiencing the same problem today. Did you get an answer on what this might be?

  • Code View Scroll Bar Jumps + High Processor usage

    In Code View, if you click at the bottom of the page -if the vertical scroll bar is present- the scroll bar jumps one or two lines up.
    I know about another bug i.e Dw uses 15 to 30% of the processor at all times, I hope it'll get fixed soon or I'll have to find an alternative.
    Lemme know if you know of any solutions.

    Windows 8 RP Build 8400 -it happened on Windows 7 as well.
    Dreamweaver Version 12.0.1 Build 5842 -I guess it's correct, I installed an update in the hopes of having this problem fixed but no luck yet.

  • 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.

  • High processor use and blank messages in Yosemite mail

    Hello
    I am noticing very high processor use from Yosemite Mail, and I am also having problems with blank messages.
    Under Mavericks, I had a problem where I double click on a mail message to open it.  The message would flash on the screen for a moment and then disappear.  The message in my inbox would be marked as read.  I could then open it again and read it normally.  Over time, I tracked this down as having to do with Mail doing anything else when I requested to open the email.  For instance, if I delete a message and then immediately try to open the next message, the problem would occur.  If I waited 5 seconds or so, then opened the next message, the problem would not occur.
    Now, under Yosemite, I find that if I open a message quickly after performing another task, the message window is blank and never fills in.  I can close that message window and open it again, it may work, or it may still be blank.  I have found where certain messages appear to be stuck and will open blank until I open a different message and then come back to the problem message.
    I have also noticed that Mail under Yosemite appears to use very high percentages of processor time.   Checking the activity monitor, Mail is third behind WindowServer and kernel_task for processor usage.  And I have another question on the community about my system running hot with the fan spooling up and down constantly under Yosemite, something that almost never happened under any of the previous OS's going back to Snow Leopard.
    Any idea what is going on with the Mail app in Yosemite?  I was excited about Mail finally advancing in capability, but it seems to have come at a cost.....  Come on Apple - Mail needs to catch up with Outlook!

    I also have this problem since Yosemite upgrade. Infuriating because I can't just read incoming emails anymore. It seems to be specific to one email account and doesn't necessarily cause a problem with others. When this happens, (showing the content for a second then disappearing), there is a segmentation fault reported in the error log.
    For me, this is a category one critical business problem. If I can't read and reply to incoming email reliably on my computer, I will need to switch to another system or device that can.
    24/10/2014 14:51:34.839 com.apple.xpc.launchd[1]: (com.apple.imfoundation.IMRemoteURLConnectionAgent) The _DirtyJetsamMemoryLimit key is not available on this platform.
    24/10/2014 14:51:36.262 com.apple.xpc.launchd[1]: (com.apple.WebKit.WebContent.A9C826DA-A925-4168-ADFD-46A9B4012097[6900]) Service exited due to signal: Segmentation fault: 11
    Good news is that the email app does seem to work a bit quicker than before using Mavericks where it could hang for 10-20 seconds for no particular reason.
    Hope this can be fixed or a workaround posted soon.

  • High cpu usage when using flash player

    Hi,
    Just updated to Mavericks and now I'm having very high cpu usage while watching streams using flash player. CPU usage is somewhere around 110% and after a moment the stream starts to lag and fps is slowing down. I also tried using Chrome but with no difference. Flash player is the newest version 11.9.900.117.
    Any ideas on how to fix this?

    i think its the best to hit the report a problem button in safari, since its appears since i updated safari to 5.1.4! maybe they make a additional update

    To reduce data usage, you should put iPad on Aeroplane Mode to stop all background activities when not using iPad.

  • Using FF 12 32-bit in Windows 7 Pro 64-bit cause high mem usage

    AVG gave an alert msg saying "detected high memory usage.
    256 MB".
    It suggest to close and open again.
    Also I notice highest page fault.
    I didn't do anything, just continue to surf as usual.
    I have 4 GB of RAM.
    Do I need to be concern about this?
    Is there a solution to fix this?
    Thanks.

    256MB of Ram isn't really "high" (depending on what you are doing). To put it into perspective. You aren't even using a 16th of your available RAM. AVG is a very poor system optimizer and anti-virus, and often provides false positives.
    You can try doing things like uninstalling add-ons you don't use: [[Disable or remove Add-ons]]
    Update your graphics Driver: [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
    Install all Windows Updates, and then test again.
    How many tabs and what were you doing when you received this alert? Did Firefox continue to run normally?
    You can view at any time how much memory Firefox is using by typing about:memory into the address bar.

  • [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.

  • Sudden high memory usage, can't find cause

    I did a big update yesterday, and today I've started to notice very high memory usage. I wasn't keeping track before so I can't say how much it increased, but I've never had problems before, and the slowness and lack of responsiveness have been noticeable, though I haven't ruled out other possible causes for that. Here's the output of 'free -m':
    total used free shared buffers cached
    Mem: 7971 7826 144 0 1 149
    -/+ buffers/cache: 7674 296
    Swap: 9215 458 8757
    It wasn't as bad as that right after startup, though usage still seemed suspiciously high. What makes this whole thing a mystery to me is that none of my running processes seem to be using that much memory!  Here's the output of 'top -b -n 1':

    I wouldn't expect the '%MEM's to add up to exactly the real usage, but this isn't even close! So, what could be using up all of my memory? I have /tmp mounted to ram, but that's only a few megabytes. I really have no idea where to go from here.
    The relevant portion of my pacman log is below, since I don't know how to get just a compact list of the updated packages. Most notably, the kernel was upgrades, from 3.9.9-1 to 3.10.3-1.

    Okay, so it turns out that this was caused by the Catalyst bug described in this post. Reverting to the 13.6 version solved the problem. Lesson learned: if there's a ton of memory being used that isn't owned by a running process, start looking for bug reports involving drivers. Especially drivers known for being, well, pretty bad. Was there any method I could have used that would have told me that Catalyst was using all my ram, or is kernel-space memory usage pretty much a black box?

  • High cpu usage for garbage collection (uptime vs total gc time)

    Hi Team,
    We have a very high cpu usage issue in the production.
    When we restart the server, the cpu idle time would be around 95% and it comes down as days goes by. Today idle cpu is 30% and it is just 6th day after the server restart.
    Environemnt details:
    Jrockit version:
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
    BEA WebLogic JRockit(TM) 1.4.2_05 JVM R24.4.0-1 (build ari-38120-20041118-1131-linux-ia32, Native Threads, GC strategy: parallel)
    Gc Algorithm: JRockit Garbage Collection System currently running strategy: Single generational, parallel mark, parallel sweep
    Number Of Processors: 4
    Max Heap Size: 1073741824
    Total Garbage Collection Time: 21:43:56.5
    Uptime: 114:33:4.1
    Total Garbage Collection Count: 420872
    Total Number Of Threads: 198
    Number Of Daemon Threads: 191
    Can you guys please tell me what would be problem in the server which causing the high cpu usage?
    One more thing I would like to know is that why the total number of threads is 198 when we specified the Executor pool size as 25? I agree that weblogic would create some threads for its maintenance but around 160 threads!!! something is wrong I guess.
    Santhosh.

    Hi,
    I'm having a similar problem, but haven't been able to resolve it yet. Troubleshooting is made even harder by the fact that this is only happening on our production server, and I've been unable to reproduce it in the lab.
    I'll post whatever findings I have and hopefully we'll be able to find a solution with the help of BEA engineers.
    In my case, I have a stand-alone Tomcat server that runs fine for about 1-2 days, and then the JVM suddenly starts using more CPU, and as a result, the server load shoots up (normal CPU utilization is ~5% but eventually goes up to ~95%; load goes from 0.1 to 4+).
    What I have found so far is that this corresponds to increased GC activity.
    Let me list my environment specs before I proceed, though:
    CPU: Dual Xeon 3.06GHz
    RAM: 2GB
    OS: RHEL4.4 (2.6.9-42.0.2.ELsmp)
    JVM build 1.5.0_03-b07 (BEA JRockit(R) (build dra-45238-20050523-2008-linux-ia32, R25.2.0-28))
    Tomcat version 5.5.12
    JAVA_OPTS="-Xms768m -Xmx768m -XXtlasize16k -XXlargeobjectlimit16k -Xverbose:memory,cpuinfo -Xverboselog:/var/log/tomcat5/jvm.log -Xverbosetimestamp"
    Here are excerpts from my verbose log (I'm getting some HT warning, not sure if that's a problem):

    So, I'm running with the default GC strategy which lets the GC pick the most suitable approach (single space or generational). It seems to switch to generational almost immediately and runs well - most GC runs are in the nursery, and only once in a while it goes through the older space.
    Now, if you look at [Sun Oct 22 02:50:27 2006], that's when everything changes. GC starts running every second (later on it's running 3 times a second) doing huge sweeps. It never goes through the nursery again, although the strategy is still generational.
    It's all downhill from this point on, and it's a matter of hours (maybe a day) before we restart the server.
    I guess my only question is: What would cause such GC behavior?
    I would appreciate your ideas/comments!
    Thanks,
    Tenyo

  • High CPU usage (more than 100%) while running video applications

    Hello everyone,
    I desperately need help with this.
    I have a late 2007 White Macbook running Mac OS X 10.6.8 :
    Model Name:          MacBook
      Model Identifier:          MacBook2,1
      Processor Name:          Intel Core 2 Duo
      Processor Speed:          2 GHz
      Number Of Processors:          1
      Total Number Of Cores:          2
      L2 Cache:          4 MB
      Memory:          3 GB
      Bus Speed:          667 MHz
    The issue that I am having is, whenever I play a video (Netflix/Silverlight player, YouTube, Skype, etc.) the CPU usage shoots up above 100% and the video or the video chat becomes VERY choppy. It becomes impossible to keep going once that starts. Originally I had 1Gb RAM (512 + 512) ... then I upgraded to (1GB + 512mb) ... it was fine for about a year and then started chocking on memory... so recently I made it (1GB +2GB) and that's when this high CPU  usage thing started (according to my knowledge)
    I have had this machine since last 4 years and its very dear to me. I dont wanna buy a new one. I will really appreciate if someone could help.

    I am spending sleepless nights, researching for a fix. From what I found so far, a considerable amount of people were able to fix this issue by simple cleaning the insides of their machines using air dusters, especially the fans. I don't know how cleaning would help with CPU utilization, but by interpolation, I feel it's worth a try. At least it will be clean, if not perfectly functional. lol
    Now the next big challenge ahead of me is getting the screws on my Macbook open. I was following the Fan Repair Guide on ifixit.com. I went and got the #00 Phillips screwdriver as suggested in the guide... came home and found out the screwdriver is too big.... went back got a #0000 Phillips (I also found out that screwdrivers with same number might be of different sizes in different stores)... got a couple of screws out and then--- another road-block!! there are a few extremely tiny Phillips screws on my macbook. Now I am hunting for the smallest Phillips screwdriver in the world. Hopefully, I will find it in some watch repair or eye-glasses repair kit in a store such as CVS or Walgreens... aaaah... this is sooo frustrating!!! I just want to get his done so that I can check it off the list of probable solutions that I want to try. Will update here if this works.
    From what you say, I think that the Silverlight upgrade might be the culprit in my case too. But the effect is there also for Youtube, Skype , or any other Video/Graphics intensive application that I use. Although, Silverlight/Netflix performs the worst among all the apps.
    I love my Macbook... don't want to part with it.

  • KDE 4.7: very slow and high disk usage

    Since upgrade to KDE 4.7 on my i686 laptop, my system behaves weirdly. I noticed a slow down caused by a very high disk usage: when the HDD spins the cpu usage reported by the CPU monitor plasmoid is very high (~ 50%), while top reports a very small CPU load. Another strange symptom is that, when I try to close the session, the system freezes for about 15 seconds before the logout/shutdown/restart dialog window appears, again with HDD spinning furiously. If I exit the dialog window and then try to close session again it works smoothly, so I think some caching is at work at second try.
    This is very painful since it slows down my workflow. Since now I tried to:
    - disable nepomuk, strigi and all that using the nepomukcontroller plasmoid
    - disable compositing
    - delete .kde folder
    - uninstall and reinstall all kde packages
    without any benefit. On the same laptop I have dual boot with a 64 bit arch installation, which does not have the same problem, nor has it my 64 bit desktop pc.
    Does anyone have similar issues? I don't understand what is it that makes the HDD spin so much, nor how to eventually track it down (are there som HDD usage profiling utilities?). Moreover, why top and CPU usage plasmoid report so different CPU usage stats?
    I'm very confused, so any help will be greatly appreciated.

    Although I'm not having any of the issues as Snack, I have found KDE 4.7.0 to be a very horrible release. In fact, I'm sick and tired of the KDE release notes bragging about killing thousands of bugs each release, when in actuality the first few revisions of each stable release are horrible. When I first upgraded, I ran into at least four really nasty bugs. Although I've worked around some of them, it left a really sour taste in my mouth. Here is what I've experienced:
    1.) With a new user or fresh install, there is no wallpaper by default, even if I install kde-wallpapers before I log in, it makes no difference.
    2.) Sometimes kwin will crash during log out.
    3.) Worse yet, if I exit a full screen game, it will more than likely crash Kwin. This is a problem on my laptop (which has intel video) and not my desktop (which has nvidia video). If I don't remember to disable desktop effects before opening a game, I may run into a problem.
    4.) Although my performance is good, it's not great. I would think a laptop with a Core i5 processor and 8GB of RAM would run faster than it is.
    I have tested XFCE for a bit, and I do like it alot. However, with XFCE I am unable to browse Samba shares, and that is a huge problem. In addition, I find KDE's applications to be much better than what ships with XFCE, but I question whether they're worth the performance hit. I really love Kate, Gwenview, Digikam, and Amarok. I know you can install those in XFCE, but they feel out of place and then my desktop pretty much becomes a mutt. Not only that, but KDE is full featured, whereas XFCE is not. It's like I have to choose between a stable desktop or a desktop with full of bugs.
    I hope that KDE 4.7.1 fixes everything, but historically it's usually the 4.x.2 release that really does the trick.

Maybe you are looking for
