I have noticed that for 2 of the sets of messages, the JMSXGroupID was generated slightly differently, because they didn't have as much information as the other messages, I am amending this, and running the test again. But, with this in mind, these messages with the smaller group ID were processed first, before the other messages.
Is this correct that it does this, and is there any way of protecting against this? Osian -- View this message in context: http://www.nabble.com/Out-Of-Order-Message-Processing-tf3446025s2354.html#a9610598 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
