Mats The behavior of sockets, even after being closed, they stick around for a little while in TIME_WAIT state. This allows acks to complete, etc.
You cannot re-open that socket until that expires. For more details, Google TIME_WAIT. If you wait a couple of minutes, can you then reconnect? If the test server is Windows, run TCPView, cuz that shows sockets that are still in TIME_WAIT state. Hope this helps!
