Dear group, I am in the process of configuring 2 new servers. They are running Centos 5.5 and for the last three days they have been rebooting unexpectedly, can you point me in the right direction what to look for in the logs. I have been checking /var/log/messages but don't see anything that hint me any clues why this is happening. Your input is much much appreciated. Lisandro PS. These are custom built Tyan boxes. -------------- next part -------------- An HTML attachment was scrubbed...

Lisandro If there aren't any messages in the logs, then I would have to think this is a hardware issue. Maybe an overheating or power supply problem. These servers have new hardware?

Also run memtest86 on them overnight (getting at least one complete iteration). That utility is available by booting the installation CD/DVD. Devin -- "Did you sleep well?" "No, I made a couple of mistakes." - Stephen Wright
They are not on a ups at the moment since these boxes are being test. Do u think this could be a power issue? ------Original Message------ From: compdoc Sender: centos-bounces at centos.org To: 'CentOS mailing list' ReplyTo: CentOS mailing list Subject: Re: [CentOS] Server reboots unexpectebly.

The thing is, that's not something centos is going to do on its own, so it's some program that's been added, or some common bios setting that's wrong.

I've seen one memtest iteration pass, but 2 or 3 were needed before a failure showed up. That's not usually the case, though... _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos Sent on the Sprint?

That's not usually the case, though...Test 5 is the most stressfull for exercising memory. You can select that to run continuously overnight.
