i'm pretty sure that's not the issue... i should be able to spawn/fork any kind of external app/process... "kill -9 pid", especially if done as root, should terminate the process... i suspect that the issue has to do with zombie processes, and how php/pnctl_exec/etc.. operates. -----Original Message----- From: ceo@xxxxxxxxx [mailto:ceo@xxxxxxxxx] Sent: Thursday, January 22, 2009 10:00 AM To: php-general@xxxxxxxxxxxxx Subject: Re: killing a child process from pcntl_exec There are functions/settings in pcntl docs about how to "listen" for specific signals. If you don't listen for -9, maybe you don't get it. http://php.net/manual/en/function.pcntl-signal.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
