The UPDATE EVENT requires a proper initialization of the session_info which in turn is used to set the tcl pcb's cmdctx. With properly defined cmdctx, the sess_data is populated successfully. But, without proper initialization of the session_info makes the cmdctx to carry incorrect vaules, thus resulting in a core when populating the sess_data.


Results in a core.


Enable the Global UPDATE-EVENT option and make sure you log some session attributes as part of the UPDATE EVENT.
