Erwin Dondorp updated ARTEMIS-3157:
-----------------------------------
Priority: Major (was: Minor)
> 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
> Priority: Major
>
> 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.
> When the cluster is started one node at a time, the effect seems to exists
> only on the first node that was started.
> Note: not related to ARTEMIS-2870 as this report is till valid in
> 2.18.0-20210322.234647-43.
