memory leaks on nginx / php-fpm

[Ensiferous]

You will want to bring this up to the PHP people as there is no link
between Nginx and PHP-FPM. There is a fastcgi abstraction layer between
them. That said, they have deprecated PHP 5.2.x and PHP-FPM for 5.2.x is
a patch so I honestly think you'll be told to upgrade first and then see
what happens, so you might want to do that first.
