Since I thought Tor only uses TCP may this be a security problem with my server?
Since UDP is a connectionless datagram protocol, there is no distinguished "listening" state. It seems more likely that those are sockets for outgoing DNS requests. Have you monitored the traffic on those ports to see what it is?
