Marshall Schor commented on UIMA-5191:
--------------------------------------
To help understand the flow, what flow controller are you using for the
Aggregate? Is it the default "fixed flow", or did you write a custom flow?
Did you specify "ActionAfterCasMultiplier" configuration parameter for the
fixed flow (if you're using that), and if so, what value did you use?
> Free instance of agreggate with cas multiplier in
> MultiprocessingAnalysisEngine

> Project: UIMA
> Issue Type: Bug
> Affects Versions: 2.8.1SDK
> Reporter: Nelson RIvera
>
> I have a aggregate analysis engine that contains 2 casmultiplier
> annotators. I instantiate this aggregate with the interface
> UIMAFramework.produceAnalysisEngine(specifier, 1, 0) for multithreaded
> processing. The last casmultiplier generate more than one cas for each
> input CAS from first casmultiplier. The issue is that after first time that
> the last casmultipler's hasNext method method returns false, the
> MultiprocessingAnalysisEngine_impl assumes that the instance of
> AggregateAnalysisEngine that processes the request has ended, and
> then this instance is free to process ahother request from other thread, and
> it is not true, because missing child cas to process from de first
> casmultipler, producing concurrency errors.
