Re: Mysterious RHEL 4 crash

Wow! Thanks a lot for your help!!!
Meantime, after several reboot, we have hard disk failure...
I wonder if it was the cause of out problem. If not... we have
one disk less and the problem unsolved! ;-|

Could you explain what is 'memtest86', please!!!
I have the same trouble: rebooting server with nothing in message log.
And I don't know how to find 'memtest86' in my RedHat4.

Try googling on it? You might find, oh, about 641,000 hits.... It tests system memory (but *not* the video card!). You cannot run anything else while it's running: you boot from the floppy or cd (the Knoppix live cd comes with it as a boot option), and you let it run. Overnight is a good time, though if you're really in a hurry, maybe two hours. It will let you know if there's harware errors in your memory.
.
You *should* have it in your toolbox as a sysadmin.

BUT IT WON'T DIAGNOSE THE VIDEO CARD!
