I compiled ssh today for my pmax box and when I 
tried to slogin to it the durn thing paniced.  Here's
the info that ended up in /var/log/messages:

Aug 10 09:37:27 pmax syslogd: restart

	I got the thing rebooted and so far I have not been 
able to reproduce this, but I am using ssh now so if there's
a problem ticked by this program I'll probably run into it
again.
