RE: Kernel crash with Red Hat 7.3 (OOPS message)

["Andreas Freyvogel" <afreyvogel ecmarket com>]

I had a similar problem but when I reboot the logs don't show anything just
before the crash as they get overwritten on boot up. Anyone have a solution
for this?

Thanks,
-Andreas

memtest can't find all of your hardware problems.  For instance, you may
be having heat issues with the CPU.

I would first boot up a Red Hat distributed kernel (the latest errata).
    Then I'd run a complex task in a loop to watch for errors.  I
usually get the sendmail or linux src.rpm and rebuild that in a loop:

while :
do
	rpmbuild --rebuild sendmail-...src.rpm
	if [ $? != 0 ]; then
		echo -n "sendmail build failed at "
		date
		break
	fi
done

If sendmail completes once, then let it run for a while (in your case,
at least a week).  If it's good once, it should always be good.  If you
come back to it, and see that sendmail build failed, after it built the
first time, then you may have hardware issues.
