Error description

  • ABEND04E RC00E2000C LOC=DSNXPCRT.DSNSVSVB+0B10 can occur when
    using parallelism.  Some storage could remain unfreed, leading
    to a storage shortage.                               (d166945)

    ABEND04E RC00E2000C at location DSNXPCRT.DSNSVSVB+0B10
    can occur when using parallelism.
    
    Storage allocated for parallelism internal structures are
    not completely freed under certain circumstances, when DB2
    goes through an error path. Accumulated storage leaked will
    cause storage abend observed in this problem.
    
    The problem is not query specific, and it could happen when
    a query is running in parallel. The query abend could be a
    victim of storage leak by previous queries.
    

Problem conclusion

  • DB2 has been fixed to free parallel storage completely
    for a query running under parallel plan. The storage
    leak no longer occurs for this circumstance.
