RE: Problem - Server stops

one of those things, yes :)  on an old box like that, it's probably heat -
cpu fans get dust in the bearings and they get slow.. anything under 4000rpm
is likely to not be fast enough to cool the processor efficiently.  Second
on my list would be RAM, and the last thing I'd check would be the CPU
itself.

Subject: Problem - Server stops


Hi 

I got problem on my server (dns, httpd, postfix, samba etc.) that running
Mandrake7.2. + PentiumII 450MHz + 256MB Memory. That server works pretty
fine since April, but today it stops 3 times. First time, there was a
server log as below. On second and third time, there was no warning sign,
server restarts suddenly with simple beep. I turned power off and on, It
boots up and works correctly.

Is this a sign of CPU, Memory hardware problem?  Overheat or something? 

Thanks in advance.
