Lou DeGenaro commented on UIMA-4347:
------------------------------------
Part 1: If JP thread sends Ack or End to JD for a Work Item not assigned
there, the transaction is marked as Rejected and the MetaCas returned is null.
> JD should tell JP when an Ack arrives late
> ------------------------------------------

> Key: UIMA-4347
> URL: https://issues.apache.org/jira/browse/UIMA-4347
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Affects Versions: 2.0.0-Ducc
> Reporter: Burn Lewis
> Assignee: Lou DeGenaro
> Priority: Minor
>
> JP should discard WI if Ack reply indicates that the Ack was too late. When
> the JD took > 2min to return the Ack the JP didn't timeout ... since the JP
> is meant to retry the Ack at least once perhaps the JD & JP should have a
> similar value for the timeout ... perhaps JP's should be longer so the JD
> doesn't have 2 outstanding Acks.
