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

Anybody know why firefox would core dump? I have no clue waht
"conftest" is... .
Grant, how oten has your system failed?

Gary,
I have owned this server since new (in 2004), and this is the
first time it has done this. I also have another PE750 that was
bought and deployed the same time as this one and it has never
done this.
I am not running anything graphical on this, so I am guessing its
not the built in video card. It is running as a server only.
Apache 2, Mysql, 4PHP4, Perl5, Exim4, vm-pop3d, ipa,
Openwebmail, and a number of add in modules for all the above.
One thing I may have neglected in my original post, is that it
appears the system may have been locked for a while since the last
log entry I can find befor the reboot was at about 12:20 am, the
system then shows the reboot at about 1:20 AM.

Gary,
Depending on the webpages, amount of memory in use, and other
things, firefox did have a tendency to crash from time to time when I
used it. Most of the time it was an indication of bugs created by
over-optimized binaries or rogue plugins / add-ons / extensions.
conftest is run by autoconf, and a signal should only be 'thrown'
(IIRC) if a test fails.
Not sure about the signal 6 (SIGABRT) and other segfault stuff though..
About the X11 comment.. actually a system that's heavier loaded than
a lighter loaded system will exhibit more issues if any exist. So the
more you run (at one time), the more problems you will see (possibly...).
Grant,
I'd check your thermal stuff then (both on your drives and your
case). What might be happening is that the machine is heating up after
extended periods of intense computation or disk use, then it reaches the
threshold operating temperature, and reboots.
HTH,
-Garrett
