Why did server reboot?

[machielr]

Hi Everyone

I hope someone can assist with some info....

We are running a SUSE 8 server (this is however general linux question) which rebooted itself during the course of the evening.


I have tried to find out what caused the reboot but from the logs I can't find the answer as none of the entries mean anything to me.


Can someone perhaps assist. Here is the entries just before the reboot from the /var/log/messages file:

thank you in advance

signal 15 was generated for some reason the logs don't show

This tells the system to shutdown. It could be a program but since you are running ver 8 ,which is very old, I expect your hardware is also very old. Could have been gamma rays or power flux or any number of random events.
