    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.
