Memory Issue

I am having an issue where a struts based application continually
uses more and more ram. I get the available memory on each pass and
manually call gc which has slowed the issue but not fixed it.

I.e:
public ActionForward view (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {

Session ses = new SessionManager().getSession();

Rooms rooms = new Rooms(ses);
Posts posts = new Posts(ses);

HttpSession session = request.getSession();

List room_list = rooms.find_all();
request.setAttribute("rooms", room_list);

List post_list = posts.full_set(new
Long(session.getAttribute("room_id").toString()));
request.setAttribute("posts", post_list);

rooms = null;
posts = null;

/* runtime variable r is declared above */
r.gc();

return mapping.findForward("done");

}

The memory usage follows this pattern:

Pass 1: (before gc) 231.4797 (after gc) 242.2315
Pass 2: (before gc) 232.2050 (after gc) 241.6035
Pass 3: (before gc) 231.8197 (after gc) 241.2478

JVM is started using (although I have tried many different
combinations of the arguments):

-server -XX:+CMSClassUnloadingEnabled -XX:PermSize=128M -
XX:MaxPermSize=128M -Xconcurrentio -XX:+UseConcMarkSweepGC -
XX:NewRatio=30 -XX:+UseParNewGC -XX:NewSize=8m -XX:MaxNewSize=8m -
Xms256m -Xmx256m -XX:MinHeapFreeRatio=70 -XX:MaxHeapFreeRatio=90

Any ideas would be greatly appreciated and if you want to see any of
the other files let me know.

Thanks in advance!
