    * PROBLEM DESCRIPTION: 1. Recovery loop in CQMMINDX+X'40C'.    *
    *                      CQM1213W message for SPACE - THREAD.    *

    * RECOMMENDATION: APPLY the PTF.                               *
    ****************************************************************
    1. Recovery loop near x'40C' in module CQMMINDX under very
    heavy workload. Additional symptom was CQM1213W message for
    SPACE - THREAD.
    2. Query Monitor tried to access the DB2 control block that
    has been already freed.
    

Problem conclusion

  • 1. Logic was changed for better memory allocation to avoid loop
    in recovery.
    2. The logic was corrected to keep actual address of that
    control block.
