CentOS randomly restarts

centoscentos5xen

My CentOS 5.7 server randomly restarts. I've found the following in /var/log/messages:

Jan 24 01:54:53 m38501 dhcpd: DHCPINFORM from 80.xxx.xxx.xxx via eth0
Jan 24 01:54:53 m38501 dhcpd: DHCPACK to 80.xxx.xxx.xxx (00:13:3e:4c:56:87) via eth0
Jan 24 01:54:53 m38501 kernel: r8169: peth0: link up
Jan 24 01:55:24 m38501 last message repeated 53 times
Jan 24 01:56:59 m38501 syslogd 1.4.1: restart.

And then it just reboots the server. It's running Xen (2.6.18-274.12.1.el5xen). Anyone knows what can cause this?

Best Answer

Check your hardware; random restarts could be cause by motherboard (there can be destended capacitor), RAM modules (often it cause a kernel panic) or by power supply.
