Don't be so quick to judge the hardware bad. Peter's experiences are
not isolated. I've had the same problems, and I know others on this
list have, too. I know my hardware is 100% good, beyond any shadow of a
doubt. However, I updated knfsd to 1.4.4, and recompiled, and I think I
changed a couple of options, to. This is 2.2.10. So far, it hasn't
crashed on me in 20 days of uptime. So Peter, you may try tweaking the
compile time options, and see if that helps. Just a thought.

To date, there has been no solution offered that I've seen. Might be
because the crashes leave absolutely no way to gather information about
why it crashed, nor do the logs ever say anything. We just walk in to
find a locked up machine, or we sit watching incredulously helpless, as
the machine spirals down to a dead state.
