Doc Type: Bug Fix
Doc Text:
If a Hot Rod client is connected to a server cluster and one of the servers is shutdown gracefully, the client keeps trying to reconnect to the server. This occurs in replicated mode. There is no failure from the application perspective but there is always a retry if the RoundRobin strategy returns the unavailable server. This might have impact on performance or even cause a failure if there is a larger cluster and a part is going out of work for some reason.

Description wfink 2014-01-29 14:55:18 UTC 
If a HotRod client is connected to a server cluster and one of the servers do a correct shutdown, the client keep try to reconnect the server after the cluster view has changed.
There is only a replicated cache configured.

From the server-logfile the new cluster view is established
16:00:22,290 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (Incoming-3,shared=udp) ISPN000094: Received new cluster view: [node1/clustered|2] (1) [node1/clustered]

There is no failure from the application perspective, but there there is always a retry if the RoundRobin return the unavailable server.
This might end in a performance or failure issue if there is a larger cluster and a part going out of work for some reason.

The original patch did not work. The new patch (currently PR) cannot be backported.

The issue is in fact not critical, I recommend closing as can't fix for JDG 6.1
