Hi Gary, I downloaded the source, compiled and ran the test - indeed it works perfectly fine. In order to understand where the problem is, I started to make changes one at a time:
1. I replaced HUB with a clean deployment of AMQ 5.5 on a remote virtual machine - no modifications to activemq.xml. So SPOKE is running locally in the unit test and HUB is a physical broker. The only reason I did this is to start/stop network myself as well (together with SocketProxy). 2. Made necessary (simple) changes to attached classes in order to bridge SPOKE with new-HUB. Test always runs successfully when I am using SocketProxy alone. However when I start/stop the network manually as the test is running, I see two different results: IF ConnectionFactory.AlwaysSyncSend is true, duplicate messages are reported on the HUB. IF ConnectionFactory.AlwaysSyncSend is false, number of messages that arrive in the HUB are less than number of messages sent. The windows commands I use to start/stop network are: netsh interface set interface "Local Area Connection" DISABLED netsh interface set interface "Local Area Connection" ENABLED I have no idea why I don't get the same results with SocketProxy but I can reproduce this whenever I run the test and play with network. I am attaching the test files that I modified here for your perusal. My changes are really simple and only to bridge a physical broker with internal SPOKE. I am happy to provide any other information you require or try any setting you suggest. http://activemq.2283324.n4.nabble.com/file/n3790910/BrokerQueueNetworkWithDisconnectTest.java BrokerQueueNetworkWithDisconnectTest.java http://activemq.2283324.n4.nabble.com/file/n3790910/JmsMultipleBrokersTestSupport.java JmsMultipleBrokersTestSupport.java http://activemq.2283324.n4.nabble.com/file/n3790910/MessageIdList.java MessageIdList.java Regards, Ozan -- View this message in context: http://activemq.2283324.n4.nabble.com/Network-of-Brokers-Duplicate-message-add-attempt-rejected-tp3771301p3790910.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
