I am using CleanSession = false to allow for offline queuing. Unless there is another way I really need this feature. > On 5 December 2012 00:27, Christian Webel <c_webel@...> wrote: > > ..if I then call removeConsumers so > > that the durable subscriptions get deactivated results to strange reconnect > > behaviour: everytime I reconnect after a connection loss, all the messages > > are pushed to my device and never deleted from the topic.

ActiveMQ 5.7, MQTT protocol with durable subscription, Android 4.1 device with latest Eclipse Paho library (jar from their site). Messages sent to the device while offline are queued as expected, but seem never to be ACKed. All offline messages ever sent to the device appear all to be sent to the device when it comes online again. Over and over again.
