Josh,
Can you tell us if you are behind a firewall? Perhaps iptables on the host
itself?
Are you running with --fork?

Well, this is very useful debugging information. I can't see how this would
lead to TCP stopping working.
When you observe that the TCP listener has died, do you get a connection
refused when you try to connect to TCP/53? Or a timeout? Or do you get a
connection but no answer?
