Trouble with socket-server on AMD64

Hi. I just changed my OS to Ubuntu Hardy AMD64 instead of Ubuntu Hardy I386. Suddenly an socket-server-application that was working fine on I386, doesnt work as expected on AMD64. The problem is with this code: <? $this->socket = stream_socket_server("tcp://" . $this->ip . ":" . $this->port) or die("Could not open socket on port " . $this->port . ".\n"); $this->watch = Gtk::io_add_watch($this->socket, GObject::IO_IN, array($this, "socketAccept")); ?> As soon as the "watcher" is set, the function "socketAccept()" will be called - even though there is no connection to the socket. This causes the code to hang, because "socketAccept()" runs this command: <? $client_socket = stream_socket_accept($this->socket); ?> I have recompiled my PHP-GTK like 3 or 4 times now with the same result. Has anyone else experienced or fixed this problem? -- Regards Kasper Johansen
