This isn't an "FYI" but rather something that should have been submitted to us as a support ticket instead of being posted on a forum. RyuLion - Please have your boss scold you for doing this by tying you up and kicking you in the balls repeatedly
Info for Elevated X Users:
1) The system once a week should run a process to clear out any old entries. If it's not doing this, please submit a support ticket to us.
2) For clients using memcached, these folders shouldn't be used.
