Hi everyone.
I have a strange problem with my DU 4.0B machine. Every once in a while, my
Apache, ircd, sshd and cron daemon processes die for no reason (that I can
find). This usually happens when I'm not logged, which just adds to the
pandemonium.
The only clues that I've managed to piece together is that these daemons are
all standalone (ie: not spawned from inetd), and the following kern.log:

I'm guessing that this is a soft reboot. Is that correct? If so, does anyone
have any idea how it could be happening without my explicit written consent?
Hunting for clues...
