I was assuming that if socket_read($socket) !== false then I should close the socket !! NO ! I must not ! If I close that socket, I have an error : 9975 Segmentation fault /usr/local/php-cgi/bin/php -q ./core.php I checked socket_last_error and I found : 104 : Connexion reset by peer .... It would be nice if the socket is checked before socket_close or socket_shutdown ... I don't know sockets system under Linux . I can't fix that :( To have the same error, create a socket, listen on it, accept accept that connexion. On the remote machine, close the telnet (kill or other :D) and then do socket_close on your socket. Then you have a seg. fault ! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16886&edit=1
