  ****************************************************************
  ISPF DSG can return "UNABLE TO RECEIVE DATA FROM CAE AGENT:
  Can't read dsect, errno 37" if the number of
  retrieved records (dsects) in Activity Summaries was huge.
  The error was not stable, it required at least 3000-5000 dsects
  generated in activity summaries, no matter what was the type of
  the drilldown (plan, authid, etc.).
  The error happened in ISPF Datasharing mode only.
  

Problem conclusion

• The fix removes the constraint to the number of retrieved
  records(dsects) and so removes error in ISPF client.
  

Temporary fix
