Annamalai commented on AMQ-2864:
--------------------------------

Thank you Gary. That's what I would expect. So with concurrent store and dispatch on a virtual
topic with persistent messages(multiple subscriber queues) , 
1. Does the producer gets released as soon as the message is published and broker gets a single
copy of the message?
OR
2. Does the producer gets released, when the messages gets copied from VT to multiple subscriber
queues and the consumers on the subscriber queues acks them.
3. Whats the risk of loosing messages on a VT with concurrent store and dispatch enabled.

> intermittent failure, activate of a durable sub and additions to the topic store may
need a sync or async store and dispatch topics may need to be disabled.
