  1. [ubuntu] LXC networking fails "randomly", reboots of the host OS fix it

    I'm getting very unpredictable results from an environment I have set up for LXC.

    I run windows 7 on my laptop, where I run a virtual box instance of ubuntu 12.10 server.

    Virtualbox is set up...
  2. [ubuntu] Re: LXC: Can I guarantee a certain level of CPU resources to a given container

    After further research it seems that LXC uses Control Groups, and control groups would be used to limit the cpu or IO utilization per container. It seems that these settings can be made in the LXC...
  3. [ubuntu] LXC: Can I guarantee a certain level of CPU resources to a given container

    We're going to use LXC to multi-purpose our hardware while keeping the various applications easy to manage, develop, upgrade, and logically segregated.

    What I want to know is if I can guarantee...

    [ubuntu] Re: fuser forking uncontrollably in cron job

    Based on a google search I found the bug below that seems to suggest this might be fixed. I wonder if afshinm's solution is still the best or if we can/should just update something to address the...
  5. Re: HOWTO: Set maximum CPU consumption in percentage by any process

    No luck, restarted and verified all cpulimit processes were gone, today I see it limiting 2 processes in the whitelist. Odd, I'll add some debug statements and will report back.
  6. Re: HOWTO: Set maximum CPU consumption in percentage by any process

    I'm 99% sure I stopped it and verified the processes, but that 1% uncertainty has a nasty tendency to assert its self. I've stopped/started and verified no cpulimit/cpulimit_daemon.sh processes.

  7. Re: HOWTO: Set maximum CPU consumption in percentage by any process

    Well, I'm no longer having cpulimit its self, but when I checked on cpulimit again today (after running a few days) I see that I have cpulimit processes on 2 of the whitelist processes. I'm...
  8. Re: HOWTO: Set maximum CPU consumption in percentage by any process

    I figured someone would comment on 3%. :) It's on an AWS micro box. Sustained CPU over about 5% will cause AWS to trigger a near shutdown of the box (98% stolen cpu). Unless the process bursts up...
  9. Re: HOWTO: Set maximum CPU consumption in percentage by any process

    Thanks for all the effort of putting up this script and helping us out with it, it's exactly what I need.

    I have been running it for about a week and found my system overrun by about 400+...
  10. [ubuntu] Re: Server hung, with ssh & webserver unresponsive for some minutes, syslogs show: ta

    Interesting. The webapp didn't seem to have any issue, I didn't note anything special in the logs and it was fully operational at the same time that SSH came back to life.

    I can't think of...
  11. [ubuntu] Re: Server hung, with ssh & webserver unresponsive for some minutes, syslogs show: ta

    It is running a java web application which consists of Jetty and a Spring based web app.

    Is there anything more than just "java caused it" that we can understand from these logs?

    I was very...
  12. [ubuntu] Server hung, with ssh & webserver unresponsive for some minutes, syslogs show: task X

    The server (natty) hung for anywhere from a few minutes to as much as maybe an hour (I'm not sure). The syslog shows some errors I can't make heads or tails of, they're attached in the hopes they...
