    Unknown magic number 10

    Annette Scherer Newbie

      I want to replicate data in a JBoss cache cluster containing two caches.
      The caches reside on two machines belonging to the same subnet (32.132.132.103 and 32.132.132.153)

      Date are not replicated. Instead I receive a RuntimeException Caused by: java.lang.Exception: Unknown magic number 10

      (note: when using two caches on the same machine 32.132.132.103, replication works fine)

      Here are service.xml and received stack:
