I've seen a problem that I *thought* was the system locking up, but actually
it was diald hanging the syslog system.
After diald runs for a while, any application that attempts to write to
the system log will hang. This includes logins, as they attempt to write
to the system log - this can make the machine look hung.
If this is your problem too, try leaving a terminal window open to the
machine, as root. When the problem occurs, go to the /etc/rc.d/init.d
directory and run "syslog stop", then "syslog start".
