This is our current plan of attack. We have another box down there and were
going to make it into an NFS server... physically move the NFS mounted drive
there... and also other NFS mounted paritions on a new drive there. We're
going to run an older version of NetBSD there on which we never had problems.
Hopefully this will at least show us if it is NFS serving that is the
However, one of these partitions is mail. And i'm horribly afraid of NFS
locking issues with multiple NFS clients reading and writing... anyone have
any opinions on whether my fears are unwarranted?

Power supplies. Ugh. I have power problems here at home, and bad/weak power
supplies do indeed cause a raft of bizarre behavior to show up... it is a
possibility perhaps. But again, a coincidence that the power would start
causing these problems just when we upgraded. I'll check with Ken as to what
we have in there.

We weren't entirely sure, to tell the truth. No one had seen it happen, and we
were remote (our top priority getting the machine back up). And there has
been no core dumps. However, as luck (?!) would have it I was down there just
last night working on it when it hung....
Everything locked up completely. The box would not respond to ping, keyboard
was dead, etc. There were no kernel messages on the monitor at all... just
the usual miscellaneous syslog noise... and then... just frozen.

I would have tried last night... but as I describe above. Everything just
freezes. Which does being to smell of hardware. But the coincidence of it
still seems too much for me.

I believe they are disabled completely. When we were having scsi controller
problems i went through the bios and made sure everything was off... i'm
pretty sure its still off.
Interesting theory though. (-: Anyhow we are full-duplex to the switch. And as
described the whole box locks...
