RE: Crashing TUX

Hi William,

Last week I had a crash again and I managed to do the ps aux | grep '
[DRZ]'. This is the output:

poison@static:~$ ps aux | grep ' [DRZ]'

I don't know what that find process is but I think it shouldn't be there.
Maybe the TUX worker 1 (PID 413) is the problem.

Do you have any ideas what could be causing these crashes?

Thanks in advance,
Nicolas Van Eenaeme

Hi Nicolas,

Are you sure your load problems are about tux? Did you checked your cron
jobs? may be it's logrotate or something like that.  When the load is
that high you can log into the system and execute this command:
	ps aux | grep ' [DRZ]'

All of the processes with state D or R are the ones generating the high
load, with this information you can identify the offending processes.

BTW, what distro and version are you using?  Right now I have a lot of
experience with Fedora Core 3.

-William
