Issue

• We have noticed a problem with the JBoss EJB client, when the remote EJB is a SLSB deployed on a 4 node JBoss EAP cluster, and the client is a web application running on
  WAS.

  After a failed EAP instance joins back in the cluster, the client creates a number of "ejb-client-cluster-node-connection-creation" threads. These threads eventually disappear,
  after about a minute.

  The problem is, that we have found that in the forementioned circumstances (client on WAS, 4 remote nodes) more and more of these threads are created each time we
  restart an EAP instance. After 5-6 restarts we see, more than 200 of these threads on the WAS.

  However, if we repeat the same test with only 2 EAP nodes instead of 4, we don't see this increase in the number of threads.

  However, when we repeat the same test, but with 4 remote instances in the EJB cluster instead of two you can see with the same command that the number of created
  threads is getting bigger and bigger every time a restarted node joins the cluster.
