--- Comment #4 from Daniel Jelinski djelinski1@gmail.com 2013-06-07 16:15:41 CDT --- Traced this one. Basically one thread attempts read data from table just after another thread (calling StopService) clears the table. Since the table is shared between all objects of the same type, this fails. Global variables causing trouble again...
