RE: [K12OSN] Random Program crashes

["Jim Kronebusch" <jim winonacotter org>]

I loaded 3.1.2 on the same box last night on a different drive and it
runs perfect.  No crashes with Gcompris or any other program.  Only
variable left is will it run just as well on the same hard drive that
4.0 is on.  I will load 4.0 today on my old test server that is running
3.1.2 currently.  I will let you know if it still crashes.  I don't know
if there is any relevance but all of my test servers are dual processor.

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.
