Bug 1806709

An EAP server setup as a HornetQ client using Discovery to locate the HornetQ JMS Brokers via UDP such as in the configuration below.  Can get into a state when there is an unknown issue occur such as a network blip, JVM Bug, OS bug where in it times out with the error below but is unable to recover and even when the network messages are received and will continue to fail with the error below.  The HornetQ UDP Clustering Client Discovery needs to be more resilient so that it can recover and reconnect.
