Hi Pasi!

Nice hearing you again :)

Thanks for the input. This box has been running Centos 3.5 for over a year 
now without any stability problems (running plain vanilla kernel 2.6). 
It's a single core Athlon64.

I guess that would pretty much rule out a hardware problem? I'll try to 
reduce the timings anyway.

Cheers!
