Hi all,

This is the first time in 10 years I have seen this.

I have a Dell PE750 (vintage 2004), running FreeBSD 6.2 that had been
up and running for about 30 days without any issues.

The server somehow rebooted last night, apparently, all by itself.

The last log file line I can find waqs about 12:30 AM. The dmesg shows
it restarted about 1:12 AM. dmesg shows some file errors that were
fixed upon reboot, other that that, everything is back up and running
normally.

I was wondering if anyone has seen anything similar and if a cause was
found.

Here is what I know:

-all servers (there are 5 more) are plugged into the same power bar
and none of the others were affected
-none of the standard logs show any intrusion or root log in attempt,
-dmesg and console log show nothing of note,
-the DRAC logs and ESM logs show nothing,
-the sensors (temp,voltage,etc) logs currently show no issues, all
well withing normal parms.
-my MRTG logs show no abnormal CPU usage or network activity.


Any help would be appreciated,

-Grant

Check the capacitors on the motherboard (in particular near the
memory and processor); they may be going bad (esp with that vintage.
2004 Dell was a bad year =P..).
You'll be looking for swelled capacitors and possibly some orange
dialectric being emitted.

Strange. In just the past few, 2 or 3 or even 4 weeks my
Dell-8200 has spontaneouslyrebooted too. I do have a number of
things in /var/log/messages, but nothing that I can seee that
would cause this problem. Before the video-card started flaking
out, this puppy ran for weeks/months happily. AFAIW, X (or a
heavily-loaded system) shouldn't have aynything to do with this
problem, [yes/no??]. Any clues, Garrett?

Ah, wait: dmesg.yesterday says
