This was observed in JBoss 4.2.1. I am inquiring the context of load balancing - example: round robin approach to picking up the messages by each node.
Alright, I have some idea of what's happening after going through -
and reading this -
The default implementation will only use other nodes if its own load is too high. Either of the List-based implementations can be used to get "round-robin" (perhaps "fair queueing" is a better term) distribution.
