Then you'll probably see that the client can't connect, and hits a timeout. At least on my German Windows box after 32 clients I get: | Warning: stream_socket_client(): unable to connect to | tcp://127.0.0.1:8080 (Es konnte keine Verbindung hergestellt werden, | da der Zielcomputer die Verbindung verweigerte.) [A connection couldn't be established, because the host refused the connection.] There seems to be a limit on allowed TCP connections; switching to UDP works fine, though. -- Christoph M. Becker
