Subject [jira] Commented: (AMQ-2543) Network of brokers with durable topics does not recover from network cable unplugging
Date Mon, 04 Jan 2010 09:39:15 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-2543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=56732#action_56732

Antti Kallonen commented on AMQ-2543:
-------------------------------------

We noticed that this issue seems to appear only with persistent topics. Persistent queues
seem to recover fine, except that message fifo ordering is not preserved on recovery. Nonpersistent
topics also seemed to recover. We also tried topics with TimedSubscriptionRecoveryPolicy,
and they also seemed to recover.

> We had a network of brokers configuration like this: C1-B1-------B2-C2 where C means
client and B broker and durable topics enabled. when we start the system, messages get delivered
correctly between clients. Even when we shut down the clients or brokers, messages get delivered
correctly. But when I remove the network plug from broker B1 severing the connection between
brokers, and reconnect the cable, messages are not delivered anymore. Brokers were set up
at store-forward configuration, with static IP:s or multicast discovery.
