destinationPolicy and producerFlowControl for large messages

[Geurt Schimmel]

Hi,

Using a destinationPolicy for dealing with large messages (23Mb):

         <policyEntry topic="LOCAL.ORATK.CFILE" producerFlowControl="true" 
memoryLimit="30mb">
                  <pendingQueuePolicy>
                    <vmQueueCursor/>
                  </pendingQueuePolicy>
          </policyEntry>

My broker hangs on flowcontrol as the topic has reached the 30Mb boundary - why 
? Sending just 1 message of 23Mb by splitting it into chunks of 10kb and 
offering them to a Camel File component. At the other end of a 
network-of-brokers a Camel File component is writing the chunks to disk. The 
only way to release the flowcontrol is to bounce the affected brokers. Why ? 
There is enough diskspace at the consumer-end, don't understand why flowcontrol 
is never released.
The poor-man's solution by setting producerFlowControle=false and slowing down 
the number of chunks offered to the Camel-component works, but that is not a 
very scalable solution.
Any ideas ?

Thanks
