Do you have any ramdisks set up or even installed? I suppose this might be a 
hardware problem but it seems that the system would crash with a boot panic 
if that was the case. I would check the boot bios memory test to see if it is 
mapping around some bad memory. I think the thing to check is what happened 
at the time the server issued the message above. See if chron or some 
scheduler is running something around that time. Also check for software 
error logs that were generated at the same time. 
Good Luck!
