Check out this patch which has been applied (9-Nov):

http://sourceforge.net/tracker/index.php?func=detail&aid=478006&group_id=5470&atid=105470

That may address your problem.  Specifically, it closes a leak in 2.2b1+.
I don't know if it affects 2.1.1.

There were a few other memory leak patchs that have been applied recently.
