David Johle created AMQ-4223:
--------------------------------
Summary: Messages being distributed to exclusive consumers!
Key: AMQ-4223
URL: https://issues.apache.org/jira/browse/AMQ-4223
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.7.0
Environment: RHEL5, Java 1.6
Reporter: David Johle
Priority: Minor
Now that AMQ-3664 is out of the way I thought I could turn on
optimizeAcknowledge back on as long as I gave it some decent timeOut &
scheduledAckInterval values.
Well, it turns out the behavior I was seeing still happens, and I think now
it's clearer that it is something else, just was partially masked by that other
issue.
My configuration is a "network of brokers" two brokers with a producer on each
one, and a consumer on each one. The consumers are set up with exclusive=true
as their part of my application is an "aggregation" step. I'm using the
exclusive mode to ensure that only one of them receives all the messages, and
the other is essentially a standby/backup in case the first one is offline.
When I have optimizeAcknowlege enabled, I see a situation where it is
distributing (fairly equally, in fact) the messages to both of the consumers.
When I set that to false, all the messages funnel into the currently active
consumer as expected.
I cannot find anything that says these are incompatible features, and cannot
figure out what it is that causes this behavior.
