In that case, you can always do a wget or cURL request to your server forcing it to clean APC cache through the webserver, I assume that if you're deploying through symlinks you want a really minimal downtime during update, the only bad thing about this method is that you need to protect the script from external visitors through htaccess or similar methods if you're using other webservers. Make the request like: wget http://localhost/apc-clear.php -O /dev/null 2>&1 man wget for more information about how to use always the correct options. If you are using Apache, you can also give a try with a graceful restart, in red hat based systems, you would restart apache with: /etc/init.d/httpd graceful or apachectl graceful I have never tried this on a production machine so I really don't know if that is gonna work, but the idea after this method is to: "The USR1 or graceful signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything)." http://httpd.apache.org/docs/2.2/stopping.html#graceful Hope this helps ^^ Met vriendelijke groet, Camilo Sperberg W: http://unreal4u.com T: http://twitter.com/unreal4u -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Yes, that is the case. And iirc it will not update the cache if the mtime of the new "switched" file is not newer.
