If there is no consumers in clustered brokers, new message will store to the specific queue on a node, but will never redistribute to another nodes even there is a consumer in the another nodes. So messages in the queue at that node can appear to be stranded.

This is the scenario:

1. start up 2 clustered broker (redistribution settings are enabled, and "redistribution-delay" is set to 0)
2. send some messages to a queue on broker-0
3. start consuming the queue on broker-1
   -> redistribution never occurs
4. send another message to a queue on broker-0
5. consumer will only receive the latest message
