Almost.
Try to compile your very-own-version of php, using configure argument
--disable-zend-memory-manager
also, disable _all_ php extensions that your scripts do not depend on.

zend memory manager won't release memory to the system. Memory held by ZMM
quickly becomes fragmented into smaller chunks than needed, so it takes from
the system
more and more "fresh" memory. Definitely this approach is not for your
situation (php daemons).
