    * PROBLEM DESCRIPTION:                                         *
    * A DB2 for zOS or iSeries client that is connecting to DB2    *
    * LUw may hang or fail with -998 when the Connection           *
    * Concentrator is enabled.                                     *
    *                                                              *
    * DB2 LUW is incorrectly switching out the connection when the *
    * Connection Concentrator is enabled. This may cause received  *
    * DRDA buffers to be incorrectly chained, or to be handled by  *
    * the wrong agent. This may cause the client to either hang or *
    * return a -998                                                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * Upgrade to DB2 v9.7 FP5                                      *
