When created a JBoss EAP 7.2 cluster on Azure and deployed a JMS Message consumer application, Then only one one of the node receives the queue and topic messages causing the single server is overloaded in spite of cluster existence.
This is intermittent situatio and there is a 50% chance that the JMS consumer load balancing works.
To elaborate more, Lets say that we have an application that consumes the messages from a Queue "MyQueue". And this application is deployed on each node of the cluster. Now when these two nodes are free and there are 10 messages posted into "MyQueue", then these two nodes ideally supposed to get 5 each. but it's not and only one gets all 10.
When we restart the one of the servers in jumbling, then it might work.
