First off, 5.4.3 is an old version that had many issues; I highly recommend upgrading.
With that said, Topic flow across a network of brokers is prone to message loss. For example, if the network connection between two brokers is lost, then non-durable Topic subscriptions between the two brokers are dropped until the connection is recreated (just as if end-clients dropped their connection and similarly lost their Topic subscription). Non-durable topic subscriptions miss all messages produced to a Topic when the subscription is not active. Are the Topic subscriptions all non-durable? Are there any signs of dropped network connections between brokers? -- View this message in context: http://activemq.2283324.n4.nabble.com/Messages-are-lost-in-a-ActiveMQ-network-message-broker-tp4694039p4694149.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
