server crashing/deadlocking



A server running freebsd 6.0 stopped responding and recovered via
remote reboot mechanism.

Some points.

(a) I have no console access.
(b) I have to pay 100 euros an hour to have someone at the console and
this isnt a viable option.
(c) No serial console or kvm is available.

Every server we have had running 6.0 in production environments so far
has had some kind of stability issue, every server except this one
(this had 6.0 fresh install) ran very well on freebsd 5.x.

The problem in this case is that the server simply stopped responding
to everything, no log entries, no kernel panic logged everything just
stopped. Is this a deadlock? if yes can debugging get it to log
anything to try and find the cause?

I had a look at the 6.1 todo list and it isnt pretty reading and it
seems 6.x has a fair few bugs, the server has sata hd's and I also
read about people upgrading to 6.1-prerelease to stop their sata
deadlocks.

I am not interested in people who want to tell me the hardware is
faulty, I can assure you it isnt.

I also want to know by enabling console.log will it catch everything
that pops up on the screen and if no how do I do that?

thanks

Chris
