Proliant DL380 G3 internittently rebooting

[Lynn Storey_1]

This server is running Red Hat Linux, and has rebooted itself several times in a months time.
I have some hardware logs, but not sure what they mean or if they may relate to the server rebooting itself. I will post the log entries below.........
