    ****************************************************************
    ECSA storage leak after SYSPLEX query parallelism thread is
    soft cancelled.
    After DB2 parallel thread acquires ECSA storage, it is cancelled
    and DB2 does not handle this error situation correctly.
    The problem is not query specific and the problem can be avoided
    by turning off the SYSPLEX parallelism support.
    

Problem conclusion

  • DB2 has been fixed to release acquired ECSA storage after
    the SYSPLEX parallel thread has been cancelled, so that
    after the fix, the storage leak problem will be fixed.
