Mysterious RHEL 4 crash

[Jason Taylor]

My server decided to crash about 10pm last night.  It just locked up.  I
came in this morning and the console was unresponsive, no virtual
terminal, nothing.  /var/log/messages doesn't show anything either.
Admittedly I am pretty new to linux, and I don't know what other logs I
can check.
