  ****************************************************************
  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.
