[jira] Commented: (AMQ-1976) Network of brokers gets out of sync
for dispatched messages causing a shutdown of the bridge connections and
stalling the brokers
[ https://issues.apache.org/activemq/browse/AMQ-1976?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=46480#action_46480 ]
Gary Tully commented on AMQ-1976:
---------------------------------
are the producers using asyncSend?
I don't know the relevance of ERROR RecoveryListenerAdapter ... but I think the assertAckMatchesDispatched is being a little harsh. My problem is reproducing the behavior.
messages that passe through a network are acked one by one. The error is telling us that the ack is ocurring out of order; since the message was dispatched, 730 other messages have been dispatched and it looks like the ack is for the 730th message. It is a valid ack though.
I think this can only happen in asyncSend, otherwise, each dispatched message is synchronously acked through to its next hop.
Ideally, it would be great if you could produce a test case. I have been trying variants of the NetworkLoadTest but am not reproducing the problem.
What does your producer look like, from the text above, it seems like there is a bunch of activity on each broker?

> Key: AMQ-1976
> URL: https://issues.apache.org/activemq/browse/AMQ-1976
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.2.0
> Reporter: Jayson Minard
>
> Running 5.2.0 RC2 + patch AMQ-1971
> I have a network of 5 brokers, running around 50,000 messages per minute per broker within each broker and sending across a total of around 20,000 messages per minute to one of the 5 brokers via a bridge connection. The configuration is the 5.2.0 default with broker names changed on each config and with a network connector set for autodiscovery.
> The system runs for a while then eventually on one broker (the receiving broker that is the only one with the consumers for this queue) these errors appear:
> ERROR RecoveryListenerAdapter - Message id ID:ingest1.mag.ss.com-54179-1223898804441-0:6:1:1:6134 could not be recovered from the data store - already dispatched
> ERROR RecoveryListenerAdapter - Message id ID:query1.mag.ss.com-38822-1223898893819-0:58:16388:1:48 could not be recovered from the data store - already dispatched
> They appear in really high counts.
> On the sending side brokers (publishers but no consumers on these brokers for this queue), these errors appear:
> INFO DemandForwardingBridge - query2.mag.ss.com bridge to query1.mag.ss.com stopped
> INFO DiscoveryNetworkConnector - Establishing network connection between from vm://query2.mag.ss.com to tcp://query1.mag.ss.com:61616
