Yes. I have run memtest for one week:
no errors.
I have also changed the mother board,
scsi controller and ram. Only the cpu
and the 2 hot swap scsi disks were
not replaced. IMHO this isn't an
hardware problem, because the kernel
with debugging options enabled didn't
crash for a long time (>1 month). Just
for record, at this moment this box is
running 2.6.22-rc4 with no debug
options enabled. I will keep you
informed.
Thanks everybody for the support.
