Error description

  • For eXtremeMemory-enabled maps, memory leaks might occur within
    eXtreme Scale servers that contain synchronous replicas. The
    leaks occur slowly and can eventually lead to exhaustion of all
    memory configured for eXtremeMemory.  At which point,
    CWOBJ7930E messages are displayed in the logs, and you must
    restart the server.

    ****************************************************************
    For eXtremeMemory-enabled maps with synchronous replicas,
    memory leaks might occur that can eventually deplete all XM
    memory. When this occurs, CWOBJ7930E messages are displayed in
    the logs, and you must restart the server.
    

Problem conclusion

  • This memory leak for synchronous replicas has been corrected.
