Thread: Suze freezes..

  1. #1

    Default Suze freezes..

    I installed 12.3 recently, having some problems lately with Suse freezing completely for shorts periods of time, longest is around 25 seconds.. then 2 or 3 seconds, then it stops freezing.. no error message is displayed or any warning at all.

    How to determine the cause ? since can't start system/monitor.

    OS version: Linux 3.7.10-1.16-default
    KDE: 4.10.5 "release 1"


    P4 2.8 Ghz, 2 GB RAM
    GPU: Radeon HD 4670 1 GB (AGP)

    3d accelerator: unknown
    Renderer: Gallium 0.4 on AMD RV730
    OpenGL/ES extension 3.0 Mesa 9.0.2
    Kernel module radeon

    open a konsole and run top and just leave it where you can see it. When freeze happens see what is eating cycles.

    Start the monitor before you run into the problem - I'd use htop in a
    terminal window myself, sort by CPU % as a start.

    When it locks up, see what it's doing using that window.

    Do you see disk activity when the freeze happens? If you do, that could
    indicate insufficient physical memory (which means it's swapping to swap
    space). I've seen this on one of my systems with less memory than it
    really should have. Solid disk activity is a sign that this may be
    happening.

    The system monitor and the 'top' command are not useful because is a total 'stop' (including mouse pointer), which means both of those tools 'froze' before indicating any process taking the CPU to 100%. The only time some indication or message was right after a long 'stop' of 25 seconds that the desktop pop up a message near the task bar that reads 'Bell in Session ' Root Shell' '. At that time I was using a 'Second Life' viewer, but the problem has happened without using that software.

    I'll check on disk activity.. didn't think of that, but I did check RAM usage, I have 2GB of ram, last time, right before the 'stop' , ram use was of only 370 MB since I wasn't using any 'heavy' software such as as graphics or even the web browser.

    Check for bad sectors in disk. smartctl long test.

    Those tools will tell you what was taking CPU up right before the freeze.

    Otherwise, look at disk activity as I suggested before.

    ok, just happened again, this time desktop did show several messages when it got out of the 'frozen' state.

    Here are some..

    What was I doing ? using chromiun (not konqueror).


    oh, no disk activity before or after the 'frozen' since it's not just one but several of different lenghts until it stops happening.

    it would really be nice to know _what_ application/utility/process is
    causing the "soft lockup"...that should be able to be learned if you
    will open top in an x-term and arrange your desktop so that you can
    see top even if you can not move your mouse...like here
    http://susepaste.org/93533969 i can see the top three most CPU/memory
    hungry processes at just a glance....without moving or clicking
    anything...and if i felt like i needed more i could adjust my desktop
    to see the top 15 processes, or more..

    oh, and turn off desktop effects and see if that solves all the
    freezes (i think maybe it is a video problem)...

    eventually you probably need to log a bug..

    Seeing the word "bug" in there, I would try Bugzilla.

    You, you could try a newer kernel version.

    Will do the things mentioned when it happens again. Lucky, it's not so frequent or I already would return to 12.2.

    I normally turn off all desktop effects and the desktop search to improve performance.


    thank you
