udp packets going to nntp server after app closed

just watching the packets go by with wireshark and trying to debug why my
nntp service is so unreliable from day to day...noticed 5 or 6 minutes
after shutting down pan, and watching the process of a traceroute with
the output from wireshark that something was sending udp packets to the
nntp server...speculation?

just shut up and run
