The default with AMQP is to start prefetching messages. However, with certain 3rd party Java tools, such as Mule this can cause a problem. Mule will create a consumer but never consume from it so any any prefetched messages will be stuck until that session is closed. This property is used to re-instate the default AMQP behaviour. The default Qpid behaviour is to prevent prefetch occurring, by starting the connection Flow Controlled, until a request for a message is made on the consumer either via a receive() or setting a message listener.
