             Summary: uneven number of connections in a cluster
                 Key: ARTEMIS-3157
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3157
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: Broker
    Affects Versions: 2.17.0
            Reporter: Erwin Dondorp


Using a cluster of 3 master + 3 slave nodes. full interconnect, each with a fresh virtual disk.

On each master nodes, the 2 static connections to the other master nodes are visible, and each is marked with the dedicated cluster username. so that part seems ok.

but without any clients having connected, there are additional connections. the amount is not the same in each master node. Some connections show "127.0.0.1" as address, something that is not in my configuration. none of the extra connections have any sessions.

the details of an example:
* broker1: 3 connections to own slave; 2 extra to/from broker2; 1 extra to/from backup of broker3
* broker2: 3 connections to own slave; 2 extra to/from broker1; 2 extra to/from broker3; 1 extra to/from slave of broker3
* broker3: 1 connection to own slave; no other extra connections

the exact amount of connections varies a little between startups and also seems to depend on the exact startup sequence.

my assumption is that these connections should not be present, and that this is not intended, hence this report. my wild guess is that these are remnants from connections that did not success due to the cluster not fully available yet.
