Subject Re: Active MQ 5.11.1 MQTT Message is automatically sent to subscriber when it is connected
Date Wed, 17 Jun 2015 12:51:39 GMT
I'm not understanding this line from your first email: "The broker is
always sent the messages which already sent to the subscriber before to the
subscriber when it is connected."  Does that mean your consumer is
consuming (and acknowledging) messages, disconnecting, reconnecting, and
receiving the same messages again?

If so, what acknowledgement mode are you using, and are you using
transactions?  If you attach JConsole to the broker and look at the
subscription just before you disconnect, do you see the subscription's
DequeueCount equal to its enqueue count?

Also, are you sure you're using the same consumer ID each time you
connect?  In JConsole you should see only one subscription on that topic,
no matter how many times you disconnect and reconnect.
