What are you using to setup your connection? fsockopen() or stream_socket_server() ? here is a snippet of what I have <?php $conn = mysql_connect(...); if ( $socket = @stream_socket_server('udp://'.LISTEN_IP.':'.LISTEN_PORT, $errno, $errstr, STREAM_SERVER_BIND) ) { while ( true ) { /* Get the exact same packet again, but remove it from the buffer this time. */ $buff = stream_socket_recvfrom($socket, 1024, 0, $remote_ip); # do stuff with your incoming data and mysql connection } fclose($socket); } mysql_close($conn); ?> I don't have a timeout set on the *_recvfrom() call. I just wait until the next connection comes in. You don't need to use mysql_pconnect(), especially if you are using, what in essence is, a daemon. Just don't open and close the connection constantly, leave it open. Also, make sure you are not using an array that you are not re-initializing through each iteration of the loop. If the array keeps getting bigger, PHP might $*%& on itself. Always re-initialize arrays to clean them up.
