Do like some services do: 1) Check if script.pid exists 2) If it doesn't 2.1) Write the process's PID onto the file (http://pt.php.net/manual/en/function.getmypid.php) 3) If it does 3.1) Die gracefully :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
