I'm sorry.  RH is bad enough, but to have it and issues too--that's rough ;-)
(Couldn't resist.)

If you try RH again (dual boot with BSD, maybe) when the network is down you
should try troubleshooting it some.  See what it takes to get the network back
up.  You can use ifconfig, unload and load modules, etc.  Write a script (same
box or different box) to check the network frequently and see how often it goes
down.  If you can narrow things down a little you can write logging scripts to
watch the network or processes or memory to see what causes the network to go
down.

If all that is too much trouble, you might try RH on a different box and see if
it works better.

Rather than setuid, I'd start Tomcat as root.  You don't have any other choices,
really.  Setuid allows anyone to run the server on port 80, and to abuse the
fact that it runs as root.  So I think running as root is better.  Apache starts
as root and then switches to a less priviledged user (if you configure it that
way) maybe Tomcat does something similar.  If this gets run by a hosting
company, they should have a way for you to get it run the way you want.
