Server reboot, why ?

saavik · 06-17-2010, 02:00 AM

Hello!

Today I found my Server rebooting without any input from me.

Now I checked /var/log/messages and /var/log/warn but I did not find any info, why the server was rebooted.

Can anybody give me a hint, how i can find out, why my server rebooted ?

Hi,

Have you checked the following:

- Output of the dmesg command (or the output of the previous one, if present on your box),
- Power outage (assuming your server starts again when the power comes back on),
- Manual/remote reboot (check with last command. ssh, or alike, logs),

Just a few things that came to mind.

Hope this helps.

My home-built server used to reboot if it got too hot. Have you checked for that?

a) dmesg
Does not give any hint
b) Power outage
could not by the problem: USV, other Servers are running
c) last
nothing

No, that isn`t it as there is aircondition and the fans are working.

What kind of server is it? i mean which kind of services are running and how many users and from where they are allowed to access?

It happens often when your system get lost of virtual memory or when hard disk not connected properly.
