System reboot by itself!

Hello Everybody;

At the last time one of my servers have an automatic reboot by itself and i dont why ??

Here are the output of the 'last' command;

[root@jester ~]# last
root pts/0 xx.xx.xx.xx Sat Dec 8 18:10 - 18:16 (00:05)
reboot system boot 2.6.9-55.0.6.ELs Sat Dec 8 17:31 (2+17:32)
root pts/0 xx.xx.xx.xx Sat Dec 8 16:45 - crash (00:46)
reboot system boot 2.6.9-55.0.6.ELs Sat Dec 8 16:41 (2+18:22)
root pts/0 xx.xx.xx.xx Sat Dec 8 16:12 - crash (00:2
reboot system boot 2.6.9-55.0.6.ELs Sat Dec 8 16:10 (2+18:53)
reboot system boot 2.6.9-55.0.6.ELs Sat Dec 8 14:53 (2+20:10)
root pts/2 xx.xx.xx.xx Fri Dec 7 12:08 - 12:29 (00:20)
root pts/1 xx.xx.xx.xx Fri Dec 7 12:08 - 12:42 (00:33)
root pts/0 xx.xx.xx.xx Fri Dec 7 12:08 - 12:27 (00:1
reboot system boot 2.6.9-55.0.6.ELs Fri Dec 7 12:04 (3+22:59)

In google i've read about it and they says this could be when the servers load is too high, but its not a certain diagnostic...

Well any tip or help, will be very helpfully!.

Regards!

Well I did get this when my CPU was overheated.

So, well server CPUs get really hot (outs hits the 126C (259F))

hope that helps.

Cheers,
Robin

But when you get this,were your server rebooted by itself too??

[RobinVossen]

Yea, thats since the CPU says.
Its to hot in here and I think ill take a break.
So the CPU stops. Then the RAM piles up and does nothing.. Now the System Either hangs or Reboots.

Failing memory can cause system reboots, too, so you might want to run some memory tests.
