Are you able to reproduce without X server running? Is this memory or CPU/scheduler related? (E.g. are you able to reproduce just with a simple cpu hog like busy loop). I cannot perform these tests at the moment, I will try them as soon as

How many processes are running/existing in the system when the hang appears? I am not sure, I hope it should not be too many processes ... cca 200? I will watch for that next freeze.

Is there any free memory (do you have swap enabled)? Yes, memory usage is at circa one half, swap is enabled with 100G space, it is almost empty all the time.

Could you run some diagnostic in the background. vmstat 1 cat /proc/schedstat (in a loop once in a while) cat /proc/sched_debug (when the problem appears) Of course, I have made a script logging vmstat and schedstat. I will attach results after next failure.

In the meantime I have switched from KDE to Fluxbox and run my computations again. I will let you know about results. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Reports against openSUSE 11.4 and prior will not get the attention needed to resolve them before openSUSE 12.2 is release and openSUSE 11.4 becomes unmaintained. Please re-test with openSUSE 12.1 or openSUSE RC2+ and re-open with an updated Product if you still encounter your issue. We apologize for this issue not getting the attention it deserves but we are focusing our resources in the area where they will have the most impact for our users. We're working hard to make openSUSE 12.2 the best openSUSE release yet! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
