      In our application we are using the below components of Jboss

       

      1. JGroups Version: 2.6.13.GA

           2. Jboss Cache Version:        3.2.2.GA

       

       

      We observed the ERROR as “failed sending message to null (191 bytes) java.lang.Exception: dest=/224.1.2.22:45222 (194 bytes)” [full stack Trace below]

      ERROR] - 07/02/16 07:12:57 -  org.jgroups.protocols.UDP --> failed sending message to null (191 bytes)

      1. java.lang.Exception: dest=/224.1.2.22:45222 (194 bytes)

      We would like to know the cause the Error and does it impact the replication of Jboss Cache across the nodes in the cluster.
