Some extra info: I managed to consistently get 1:1 in my request/response code. I did this by changing the redeliverypolicy.maximumRedeliveries to 0. I don't like this solution, but suggests that problem is acknowledgement of messages. I have previously acknowledge in the code by calling the msg.acknowledge method. This do not solve the problem.
Another observation is that the problem does not exist when the request/response messages are called on the same connection. It is does show when the response code is running in a windows service, and request is called from a client on a different machine. Any ideas what the hopefully simple problem is? -- View this message in context: http://activemq.2283324.n4.nabble.com/Receiving-multiple-duplicate-messages-Beginner-question-tp4706474p4706607.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
