      Opening a new subtask as it's bit different from other issues.

      In this scenario, I did the following:

      1. Start Broker 10 and populate my CMG.OUT queue with with 5000 messages.
      2. Started 8 brokers and allowed the fan out process to complete. Took ~ 11 minutes
      3. Started my consumers. There were some duplicates flying around but I saw my connections start dropping after period of time. Many consumers were left waiting for a significant number of messages. In the attached screenshot we can see store ST10272. On the left hand side we have broker 2 who says he has 571 messages and has a network consumer from broker1. On the right had side broker 1 who shows a local consumer. No messages are moving.
      4. I stopped broker2, and restarted. The consumer on broker1 moved to broker 8 as did broker2. The messages were then received and that consumer finished.
