> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Lou DeGenaro
> Assignee: Jerry Cwiklik
> Priority: Minor
> Fix For: 2.2.2-Ducc
>
>
> Apache DUCC demo has PM that runs with reduced memory -Xmx200M
> On at least 2 occasions PM has taken OOM. Core dumps have resulted that
> indicate that PM is flooded with multiple OR publications that is supposed to
> be handled by "BlastGuard"?
> Investigate what storage is being used for and if multiple OR messages are
> being processed in parallel. Perhaps Camel should be configured to process
> OR message sequentially if it isn't already.
