Re: FreeBSD 5.1-R kernel panic

Hi Bosko,

I've setup a cronjob every 5 minutes to e-mail me the requested data "sysctl
vm.zone".

The crashing is re-occuring, it seems to happen every day and a half or so.
We did not fix the problem, but we did leave it at about a week and half ago
when you suggested to update to -CURRENT from -RELEASE.  This past weekend,
I finally got to updating to -CURRENT (I deleted my /usr/src then cvsup'd
src-all from HEAD (.).

Also, System Load is way higher then it was in -RELEASE around 10.00 -
20.00.  I'm assuming this is due to all the debug options enabled
in -CURRENT.  Anything I can disable to lower the average load but continue
to troubleshoot this problem?  Some of the debug options which may not be
helpful at this point perhaps?

If I reboot the server on a nightly bassis, I can get away from the
crashing, but rebooting every night is quickly becoming old and would rather
have this fixed up.  Again the problem seems to occur every 1.5 - 2 days.

Let me know if there is anything else I can provide to help find a solution
to this problem.

Thanks,
Stephane.
