I once had a similar problem where the server would go down for no
apparent reason, and with no indication in any of the logs as to why
it would crash?  The problem turned out to be the hard drive failing.
I isolated the problem by attaching a printer to the serial port to
monitor the console messages which lead me to the hard drive.  Give it
a try!
