    PROBLEM SUMMARY:
    When a DB2 subsystem is monitored by a PE Server subtask and
    function Snapshot History is activated, Snapshot History may
    discontinue data collection because it is waiting for the
    completion of a data retrieval request. The data retrieval
    request from Snapshot History becomes orphan in the input queue
    of the data retrieval task because simultaneous access of
    parallel tasks is not correctly serialized.
    
    PROBLEM CONCLUSION:
    The code has been corrected accordingly.
