----------------------------------

             Summary: Got duplicated messages when using ha-policy-autobackup
                 Key: ARTEMIS-2511
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2511
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: ActiveMQ-Artemis-Native
    Affects Versions: 2.10.1
            Reporter: Ning Kang
            Assignee: Clebert Suconic


I tried the example from this link, but found a bug of duplicated messages and 2 other issues.

[https://github.com/apache/activemq-artemis/tree/master/examples/features/ha/ha-policy-autobackup]

 

When finish step 16 in HAPolicyAutoBackupExample, if I restart server1 and consumer1, then all scaled down messages that already consumed in step 16 by consumer0 will be received again by consumer1.

 

To reproduce this bug, just follow the setup in the ha-policy-autobackup example, and add the follow steps after step 16 in HAPolicyAutoBackupExample,java, 

16a: restart server 1

16b: restart consumer1

16c: consumer1 will receive all scaled down messages that already consumed by consumer0

 

Is this a bug of Artemis HA, or there is some extra configurations need to be made in broker.xml to avoid scaled down messages to be consumed again?

 

*Another 2 issues I found related to this example are:*

1. After restart server1, both server0 and server1 will continuously do RequestBackupVote actions and never stop, is this normal? See example log
{code:java}
2019-10-03 17:26:37,916 INFO [org.apache.activemq.artemis.core.server] AMQ221063: Sending quorum vote response: RequestBackupVote [backupsSize=1, nodeID=1905cb70-e508-11e9-8290-00505680c5d7, backupAvailable=false]
2019-10-03 17:26:38,926 INFO [org.apache.activemq.artemis.core.server] AMQ221062: Received quorum vote request: RequestBackupVote [backupsSize=-1, nodeID=null, backupAvailable=false]{code}
 

2. Even if server1 is restarted, the loadbalancer is not working any more. All messages from procedurer0 will only be sent to server0, instead of half of messages sent to server0, another half sent to server1.

 

Thank you and waiting for your reply.
