Hi, There is a bug in the current implementation of NMS-AMQP ( https://issues.apache.org/jira/browse/AMQNET-608) that results in sending transfer frames on sender link as settled even when sender settled mode is Unsettled. This is against AMQP spec. There is at least one broker that detaches the sender link when a non-persistent(settled) message is sent - I believe it is Solace Broker. This particular scenario affects only messages sent in a fire and forget manner.
One of the proposed solutions is to simply set settled flag to false for all of the sent messages. The other is to use different settled mode for the sender link, e.i. Mixed. The third solution would involve implementing presettle policy in the same way as there is implemented in qpid jms. I'd love your advice on this. Thanks, Krzysztof Porebski
