  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 

  rl0: link state changed to UP
  pid 729 (Xorg), uid 0: exited on signal 6 (core dumped)
  pid 4475 (Xorg), uid 0: exited on signal 6 (core dumped)

  Anybody know why firefox would core dump? I have no clue waht
  "conftest" is... .

  Grant, how oten has your system failed?


  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.
