Many thanks, today I managed to raise an exception in CommandPASV(), "port in use". The port table reported the port as free, although the server actually was listening on that port. I was clicking around in multiple FTP clients when that happened. Unfortunately, subsequently I wasn't able to reproduce the same error again. But there must be a rare condition that causes the port to be removed from the table even though the socket is still listening and not closed, very strange, I tried 2 hours until a gave up.
