Hi all,

I have one server running redhat AS 2.1. This server suddenly reboot last night and half month ago. There is no error/message logged before and after the reboot.

Does anyone can idea to trace and trouble-shoot this kind of problems?

Thanks and best regards,
Tony Sung

no errors / message in /var/log/message*.

then it is difficult to reboot.

i would start by checking the disks. if there is any bad blocks or something like that.

and am clueless since there is no error logs.

Hello!

Check the logs /var/log/message
For errors

You didn't write what kind of machine you have.
Do you have some suite for the server to check
in boot the problems of machine?

If the server was hooked to a UPS and configured there should be a message.

Unless the server's own power supply suddenly failed.

That will leave very little evidence, perhaps some log messages at boot because the filesystems were not closed cleanly.

I'd look at the power supply first. These type of problems rarely happen just once. Unless the problem was the cleaning staff hitting a button or pulling out a cord, it will happen again.

Dear all,

As there is no error in the /var/log/messages,
I find difficult to troubleshoot.
It is a ProLiant DL580G2 server with dual power supply connecting to two UPS, I am not sure if it is a power failure.

Thank a lot for your comment.

Does it happen to have lots of memory (2-4GB)?

And if it does, did it reboot in the middle of a IO intensive operation (A backup maybe?).

What processes were running on the machine at the time of the reboot?

Do the system load, memory usage, etc go up in a pattern that is repeated each 15 days? Start monitoring these and if you get another reboot analyse them.

Good luck,
Cristi

What network module driver is it using?

I didn't think the AS2.1 had an issue with the 'tg3' driver, but it might (if you haven't updated any eratta that exists).
