Number of listeners on the MDB I think. Multi processing.
We had the same number of listeners on the MDB(the default 15) and the jmx-console on the HornetQ2.2.1 always showed only connection per IP.
But when we upgraded to HornetQ2.2.5 we now see 15 connections listed(even when there is no messaging activity). So has soemthing related to the netty connection management changed from 2.2.1 to 2.2.5?
