> When a work item ends due to normal completion or exception, the JD proceeds to cancel the corresponding Ack/End timer.  Unfortunately if a JP is preempted or autonomously ends the timer is not reclaimed (hence, the bug).  When the number of these non-reclaim events gets large, the potential exists for JD to go OOM.
