This is a typical socket address condition that can't be safely overridden by hand. If you look at your net stats, the socket in question is probably in a CLOSE_WAIT state. This is a subsystem status that says the remote has shutdown and it's waiting for the socket to close and cleanup. If the socket gets dumped improperly by the socket application, then the socket can be left in CLOSE_WAIT with no process attached to finish cleanup. The status will clear up, but it could take a long time. That all depends on the tcp_close_wait setup and whether or not the socket is setup with the SO_LINGER flag. If the socket's SO_REUSEADDR flag can be enabled using some kind of U2 "setsocketopt" function before you listen on it, then you can re-use the same socket address over and over again.
