-------------------------------
Fix Version/s: 2.0.0-Ducc
> DUCC Job Driver (JD) sometimes fails to cancel timers for Ack/End
> -----------------------------------------------------------------
>
> Key: UIMA-4313
> URL: https://issues.apache.org/jira/browse/UIMA-4313
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Affects Versions: 2.0.0-Ducc
> Reporter: Lou DeGenaro
> Assignee: Lou DeGenaro
> Priority: Minor
> Fix For: 2.0.0-Ducc
>
>
> 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.
