> I have been trying to get my head around the multicast discovery mechanism.  
> In particular its use of the “FailoverTransport” class is bothering me.  The 
> issue presented itself when viewing the DEBUG level log entries that were 
> generated after one broker of a pair, connected using this discovery 
> mechanism, was stopped.  The FailoverTransport went into a very tight endless 
> loop of attempts to reconnect.
> My first thought to “tweak” the Failover properties in the network connector 
> URI.  But alais, the uri was for the multicast not the failover.  No problem, 
> just duplicate the failover properties on the multicast agent.  After doing 
> so, I started to think “why is failover needed at all”  won’t the connection 
> be reestablished when the broker returns and advertises itself again?
> Can someone comment on this issue?  Is the bug that the failover properties 
> where not available or is the problem that failover was used at all?
