Good Morning,

We have a server at the office loaded with Slackware 9.0

All patches are current to the best of my knowledge....

Specs are as follows:
2.2Ghz
512MB RAM
Promise RAID Controller (RAID 1)

ClamAV
Qmail
Apache
Bind
FTP

Kernel 2.4.23

The problem is...

First Problem: About every three days or so, it hangs, randomly, at any point of the day.

Second Problem: There is nothing showing up in any of the log files, it literally stops responding

Third Problem: ClamAV was installed just prior to me starting here and apparently there were no problems with anything.

As stated, it just simply stops responding and e-mail does not get through, browsing stops and DNS is unresponsive.

Any ideas on where I perhaps could start investigating.

Thanks in Advance!

Cheers!

Well, you might start with hdparm.......it could be set to spin down the drives to save power after a certain amount of time of inactivity........

You have mentioned it doesn't respond to network services, what is the story if you try to logon to the console? The only box I've had that died like this didn't like APIC support being enabled in the kernel. Once that was disabled it was fine. I've still got no idea exactly what was causing the problem as it was dying silently.

cheers

Jamie...

Are you using NVIDIA drivers on it? My computer used to lock up sometimes when I had agpart loading. Once I recompiled the 2.6 kernel and removed apgart my computer has been working fine.

Interesting... my box was an NForce2/Nvidia box too...

Hi there,

Thanks for the responses.

hdparm does not show any inidcation of spinning down the drives.

As for the network not responding, this even goes for the console. I have to give it the magic 5 second count down on the magic button and reboot before it is ok, obviously, this is not the way I want to resolve it.

As for Nvidia, no, it's a plain vanilla white box with integrated everything, no X and ran great since installed with the exception of lately.

Cheers!

It sounds like you suspect the AV program.
Can you run without it for 3 days to see if it is responsible?
Maybe you could use an alternative av program temporarily to test this.
The lack of software errors might suggest a hardware problem. Perhaps you could test this by using an alternative computer for a while?
You say that the network fails, but as it is a server, I guess that this is what you notice, so do other apps fail, or is it just the email stuff?
