-------------------------------------
Jerry - do we need to update some documentation about this, somewhere?
> Provide a way to drain Dead Letter Queue
> -----------------------------------------
>
> Key: UIMA-927
> URL: https://issues.apache.org/jira/browse/UIMA-927
> Project: UIMA
> Issue Type: Improvement
> Components: Async Scaleout
> Affects Versions: 2.3AS
> Reporter: Jerry Cwiklik
> Priority: Minor
>
> ActiveMQ currently doesnt evict expried messages from the Dead Letter Queue.
> This can potentially lead to Out Of Memory situation as by default the broker
> keeps all messages in memory. One possible strategy is to modify ActiveMQ
> broker configuration to spool messages from the DLQ to disk when memory is
> tight. Other strategy may involve creating a custom DLQ Consumer to drain
> messages.
