I send acknowledge for lists of 500 messages. So it is probably, bug in client's Session implementation, the way it interprets server responses.

It means the client should not receive more than 10000 *unacknowledged* messages. If your client acknowledges messages as it receives them then it should continue to receive messages. You can set flow control to unlimited but your client needs to acknowledge messages in any case for them to be removed from the queue. You can set your subscription such that no acknowledgment is required but I don't know the .NET API to do so. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:dev-subscr...@qpid.apache.org --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:dev-subscr...@qpid.apache.org
