             Summary: JCA RA inflow connections are not always well balanced
                 Key: WFLY-10102
                 URL: https://issues.jboss.org/browse/WFLY-10102
             Project: WildFly
          Issue Type: Bug
          Components: JMS
    Affects Versions: 12.0.0.Final
            Reporter: Erich Duda
            Assignee: Jeff Mesnil
         Attachments: server1-trace.1.zip, server1-trace.2.zip, server1-trace.3.zip, server1-trace.zip, server1.zip, server2-logs.zip, server3-logs.zip, server4-logs.zip, test.log.zip

*Scenario*
* There are 4 Wildfly servers. Severs 1, 3 are in cluster.
* Queue InQueue is deployed to servers 1,3.
* Servers 2 and 4 have RA configured to connect to servers 1 and 3 server.
* Start servers 1,3 and send 10000 (~1Kb) messages to InQueue
* Start servers 2,4 with MDB consuming messages from InQueue and sending to OutQueue.
* When MDBs are processing messages, restart (clean shutdown and start) servers in this order: 1,2,4,3
* Wait until all messages are processed.
* Measure number of consumers on InQueue on servers 1 and 3.
* Difference between number of consumers must be <= 2.

*Expectation:* Number of consumers on servers 1 and 3 are almost equal.
*Reality:* Number of consumers on servers 1 and 3 are sometimes different. E.g. server 1 has 19 consumers and server 3 has 11 consumers.

Note: this is not regression. I can see this issue also with Artemis 1.5.x.
