Maybe I can!

I have problems too and there no specific program or load level. It just
freeze. Whole computer. Only network card remains pingable.
Within 3 days it happens 4 times. Every night once (and without any load
at all). Between 2AM and 3AM. And once yesterday 3PM, mid working day.
Every other days it could be hang, but I compiled kernels and therefore
restarted server every hour or less.

So, I think, problem is in default kernel 2.4.22-1.2135.nptlsmp. It
hangs after 5..6 hour from restart here.
Also, As I noticed, freezing was only with SMP machine with SMP kernel.
(I never tried uniprocessor kernel with SMP machine - it is production
machine)

I compiled new kernel 2.4.23 and tonight was without freezing. But this
is not solution!! With 2.4.23 I cannot run wine! It just give
"Segmentation fault". Also i tried working .conf from original kernel
sources.
Wine works only with kernel (or sources) shipped with K12LTSP4 ISO!
Even downloaded 2.4.22 compiled with original kernel .config not work.
I tried with 3 different kernel and 2 different computer.
One was SMP and another single machine.

Self-compiled 2.4.21 kernel, K12LTSP2.1.3 and wine worked perfectly.
But there was a little bit older wine (3 month ago)
With Fedora I tried wine RPM for fedora.

Today morning I switched to stripped compilation of shipped kernel
sources. If it also crashes within 7 hours, I inform you. 

Mella, no ideas any more.
