We are facing couple of issues with ActiveMQ - MCollective load balancing. Can someone please help? Below is our setup

MCO has two ActiveMQ brokers configured in failover pool - Broker1 & Broker2. And we have set randomize property to true in server.cfg and client.cfg.

Broker1 & Broker2 together form an activemq cluster. They also have updateClientCluster and rebalanceClientCluster properties set to true (set on both activemq brokers).

Issue1: MCO clients are not equally load balanced and connected between broker1 and broker2. 700 MCO are connected to Broker1 whereas only 100 MCO connected to broker2. Are we missing any property for this loadbalancing ?

Issue2: When we add a new broker, say broker3 to activemq cluster, the MCO clients are not getting rebalanced or connecting to new broker. As per activemq documentation, if we enable updateClientCluster and rebalanceClientCluster properties, it should automatically notify MCO to rebalance. Can you please let us know any properties.

Attaching activemq.xml, server.cfg and client.cfg. Thanks in Advance.
