I think what you are saying is correct from the broker's perspective. I tried coding up an example without using camel and I do not see the same behavior.
The example can be found here http://s000.tinyupload.com/?file_id=62097383795604422204 I am not sure sure I coded up the example correctly. I am very new to ActiveMQ and Camel. Any ideas on how I can configure Camel and ActiveMQ to generate only 1 message? Maybe have the consumer send the ACK immediately upon receiving the message? -- View this message in context: http://activemq.2283324.n4.nabble.com/Behavior-when-a-message-expires-while-it-is-processing-tp4680241p4680287.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
