Trouble with server crashing

[Jayesh]

Hi,

There are few server which are crashing for no reason. The servers are
running FreeBSD 5.4 Release. To check if the issue was related to h/w we did
change the h/w once. The server is web server with cpanel installed.

The /var/log/messages doesn't have any info regarding the server crash. The
server just gets rebooted.

Please guide me on what all need to be checked so as to resolve the
situation.
