I came in to work this morning to find my machine in a rather strange
state.  It wasn't completely hard locked, but I could not log in with
my NIS username and password.  Looking around in /var/log/messages, I
found the following information:

As far as I know, the machine had just been sitting idle since I left
work yesterday.  This is with Fedora Core 2, autofs-4.1.2-2,
kernel-2.6.5-1.358.  Please let me know if there's anything else I can
do to provide you more information.
