Thanks for your answer, I got your point regarding "in delivery" messages.
Is there any wait to max the number of "in delivery" message, because it seems if I have at least one consumer connected there is no wait to make use of LVQ. I tried to configure "jms.prefetchPolicy.all=1" to test but it works in the same wait. so, it seems to me LVQ functionality is only valid when you are not in cluster and when using durable queues where no consumer can be connected to later connect and get messages, is that correct?
