    ****************************************************************
    With DB2 10, several blocks were moved above the bar to store
    message output for DISPLAY THREAD commands with the option
    SCOPE(GROUP).
    .
    When there are messages sent back from other
    datasharing members in the group, DB2 was not freeing these
    above the bar blocks at the end of the command, resulting in
    the reported storage leak.
    

Problem conclusion

  • DB2 has been modified to free the storage once the
    output message is no longer needed.
