Then your *users* are in trouble - as I wrote later in the mail ;o) There's no check to see if 'rootpages' contains some strange or high value. But 'rootpages' doesn't affect UID 0 operations. Root *can* eat all memory if (s)he likes ...
OTOH, rootpages is meant to be set during initialization of the system (like after /proc is mounted) ...........
Kind regards,
Brian
