I have a 486 machine that I have used as a firewall for the past year.
It has been very stable until recently.  Four days ago, it locked up.
No response from either the network or the serial console.  Nada,
nothing.

So I powered it down and back up.  It booted fine and fsck took care
of the disk problems on reboot.  I looked in /var/log/messages (all
console messages are directed there) and found no errors so I just
shrugged my shoulders and didn't worry about it.

Now four days later, the machine locked up again.  Same thing, no
response.  After power cycling, there were no errors in
/var/log/messages.  I upgraded from 4.4-RELEASE to 4.5-RELEASE on or
about Feb. 18.  Other than that, there have been no changes.  What can
I do to determine what the problem might be?  Are there any diagnostic
tools in the ports I should try?  I'm really at a loss here as to
where I should start.  Any suggestions appreciated.

Thanks,

Drew
