Description

 

Steps to produce, using a producing application (running AMQPNetLite) connecting to node1 of the cluster:

• Create queue1, publish 199 messages to it
• Create queue2, publish 1 message to it

Running a consuming application (AMQPNetLite) connecting to node2 of the cluster:

• On node1 of the cluster, queue1 & queue2 now have 0 messages in it
• On node2 of the cluster, queue1 has 200 messages in it and queue2 has 2 messages in it (i.e. an additional message in each queue, even though the consuming application is not publishing any messages).
• The consuming application connected to node2 of the cluster does not consume any messages off either queue1 or queue2 from node2 (of the cluster).

In artemis.log on node2 of the cluster, the following appears:
