    org.jgroups.protocols.UDP --> failed sending message to null

    Bagavathi S Newbie

      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)

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