Christofer Dutz commented on FLEX-34648:
----------------------------------------

Ok ... sorry for posting that much, but the picture ist getting clearer and clearer :-)

So it seems the message-timeout is only used while a client is actively polling the queue
as the cleaning up is done in the flush method of the FlexClientOutboundQueueProcessor. As
soon as the Client has sopped polling this method is no longer called causing the messages
to remain in the queue, even if they have expired.

Eventually it would be good to have some sort of MessageExpirationThread that continuously
cleans up queues. 

But now the symptoms we have observed seem to make some sense.

> a memory leak occurred when sending alot of AsyncMessage through BLAZEDS in a real time
systems which is heavilly using messaging however we are increasing the jvm heap size  to
4 GB 80% of the size is occupied by AsyncMessage objects this is very clear from the generated
heap dump.
