Machine gateway/firewall/NAT box and is crashing and rebooting every 3 or 4 days,

>How-To-Repeat:
This crash is from 3PM today. I was running tinyfugue connected to 1 MUD.
I may have had tinyfugue backgrounded and may have been running PINE. Very
light network traffic and just myself on the machine (which is the norm
unless I am playing some network games).
