Exact. The consumer which had the 2 messages is the one which is supposed to get the 5 messages. It's a consumer-broker created by another cloud service supposed to consume the 5 messages sent.
It looks like the 2nd consumer with the 3 messages is created by the producer. But 5 messages have been produced and no broker has been configured on the producer side. Maybe it's a networked broker as you mentioned but how can I confirm. As I said no broker has been configured to get created by the producer and 3 of the 5 messages are not consumed by the correct broker. Explanations I see: * the 2nd broker is created by the producer but why 3 messages are consumed not 5? * the 1st broker has not enough time to consume the message and a 2nd default broker consumes it They are only hypothesis, I am not sure how to confirm and fix the issue. Below the producer properties: <http://activemq.2283324.n4.nabble.com/file/t378791/Picture2.png> Thanks for your time and help. -AEB -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
