Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of Websphere eXtreme Scale who    *
    *                  use ObjectMap.clear and use asynchronous    *
    *                  replicas or multimaster replication.        *
    ****************************************************************
    * PROBLEM DESCRIPTION: When clearing a map, some replicas      *
    *                      can still have entries in them, while   *
    *                      other map entires are correctly         *
    *                      cleared.                                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A window of time exists where a replica can report that it
    received a clear operation when it actually did not.  The fix
    for this problem puts in logic to handle this window of time.
    

Problem conclusion

  • The fix for this problem was fixed in the 8.5 release.  The
