If you set "QUESTS=on", it might help to show if you have any quest issues that could be causing weird issues.

Other than that, a work-around for your problem might be to set the zone to do a daily reset using my Zone Reset Script posted in the custom quest section of the forums. Resetting the zone should clear out any RAM usage.
