Linux crashes

[fernandoflorez]

Hello guys,

Sorry if this is not the right forum but i don't see anywhere else to post about my problem.

I installed zimbra on a centos 4.4 server. Everything went so nice that i installed it on a production server also running centos 4.4. The problem i'm facing now is that the production server crashes every X days.

When the server crashes it doesn't even let me execute any bash command

Any ideas?

Sorry again if this is not the right forum.

Thanks,
Fernando

You're about to wake up MarcMarc with this question

What does your hardware look like? Do you have enough ram?

[fernandoflorez]

The server has 2 80 gb hd (raid 1 with lvm), 1.5 gb ram, pIV 2.8, etc.

top says that there are less than 400 mb in use currently.

Im sure its a hardware problem but how can i know exactly?

Thanks!
Fernando

Wow-
If things are that bad, the first thing you need to do is create an off machine backup.

That defenetly sounds like a hardware issue. Have you tried running an disk check for integrity? In my experence, the following are the type of things that can cause that kind of problem:

Power Supply
Hard drive (Bad sectors/integrity)
RAM
Overheating

I'm between an overheating problem (i have seen that server get up to 38°) or a raid lvm problem. Don't know really...

Thanks for the help! I'll look into that!
