A blocking socket will not detect an abnormal disconnect until the underlying socket stack itself decides that the socket is no longer valid. That will not happen right away. In fact, it could take a long while. The stack will not be able to invalidate the socket until it begins timing out internally. Those timeouts are fairly large by default. > I'm using lot's of clients, and I dont want the network > traffic to be to high just for sending "keep alive" messages. That is exactly what you should be doing, though. That is the only reliable way to detect an abnormal disconnect in a timely fashion. Gambit
