okay i'm confused, apologies for my ignorance i'm not much of a programmer
(more of a perl/python hack).
why would the application itself be limited?
and is the limit with linux 2.4 3gb or 4gb of memory per process. i've
had different people say directly conflicting stuff to me in personal
email from posts to this list (which was my general experience trying to
figure this out on the web as well).

unfortunately i don't think they do, so that's not an option. i only
started working here a week ago so there's a lot i don't know about the
appliations we run, i'm just trying to get an overview of what's possible
so i can begin architecting sensible tests and set my boss' expectations
