I suppose it depends on what you're doing, which, unfortunately, I don't
know.

If you're overly filling your session w/ objects, or if you have a session
scoped bean that is spiraling out of control or something, that might lead
to the problem, or if you create/leave open jdbc connections or stuff like
that.  I'm running tomcat 4.03 on a much less beefy system, and I don't ever
notice any memory issues, now that I make sure I close and null my
connections and such.

More info on what's happening might help, though..
