[Gllug] Unexpected server reboot

[Simon Morris]

Hello,

Today a server decided to reboot itself and I can't find a logical
reason why it happened.

The server is an IBM x3850 running RHEL5.

Looking in the log files I find...

[root at LON0WEBNATIVE01 log]# grep -r 'Jun 16 07:50' *

The server seems to have shut itself down cleanly and then come back
up. 

There is one instance of a similar problem [1] but I was wondering if
anyone else had seen this before or had a clue

Thanks
