  .
  Looks like an 'invalid' return area has caused the high CPU
  consumption when the return area
  is screened  for desired IFCIDs because we may have passed the
  normal end of the return area.
  Base on the job output the data server reported an invalid
  return area and an SDUMP with the name of
   'INCORRECT RETURN AREA - SCO1'.
  is produced.

Problem conclusion

• When performance data are requested from the PE Client and the
  data server detects invalid data to be returned, the data server
  initiates an SDUMP with title 'DGOVSCO1 - INCORRECT RETURN AREA
  xxxxxxxx' to save the invalid return area for later analysis.
  The dump title contains the address xxxxxxxx of the data area
  which contains the invalid data.
  When invalid data are detected further processing is immediately
  discontinued and the error condition is returned to the PE
  Client.
  The data server and PE Client will be available thereafter for
  normal operation.
