Hi. I am the author or AiP. There were a lot of leaks, when I tried this idea originally, back in php 5.2 days. See http://blog.milkfarmsoft.com/2007/06/php-as-appserver-vs-memory-leaks/ http://blog.milkfarmsoft.com/2007/06/php-as-appserver-vs-mem... for example. But 5.3 solved all of the issues. The only leaks happening these days come from "unofficial" extensions, which introduce errors on C-level. PHP code _never_ results in memory leaks these days, as far as I know.
