are you sure the server restarts by itself?

It's funny that: centos-webpanel.com has cPanel and not CWP installed.

Did you checked your history? Just write "history" and check if somewhere there is "shutdown -r ***" or "reboot".

Hi,

Please run last reboot command and check cron log, messages log, ssh secure log.

[root@ ~]# last reboot
