After a week of not getting to touch the box, I've run a few more 
tests..  It turns out it's not a firewall related problem at all.  I 
booted up the machine with iptables off to be sure the modules weren't 
loaded.  After about 6 hours, all communication with the outside via 
eth0 ceased.  The ssh session I had open reported 'connection reset by 
peer' and dropped.  I was able to continue sending and receiving via 
eth1 (both cards are intel ethernet pro 100s).  As I said before, after 
this problem occurs, the computer still sees the traffic (as shown by 
iptables -vL), but no longer acts upon it.

Any speculation?
