  ****************************************************************
  PROBLEM SUMMARY:
  1. The PE Client is set up to automatically refresh the Data
  Server KPIs in the System Overview window. On PE Server subtask
  side the usage of memory in subpool 0 key 8 continuously
  increases and finally causes various abends as soon as storage
  is exhausted.
  2. The performance data returned from DB2 as response to an
  IFI READS request with group scope are scanned for IFCID 2
  data. The first found IFCID is processed and consecutive IFCIDs
  are then skipped.
  
  PROBLEM CONCLUSION:
  1. The code has been corrected and the PE Server subtask trace
  has been extended to report storage allocations if the PE
  Server subtask trace level 64 is set.
  2. All provided IFCID 2 data from all contributing members of
  the data sharing group are processed for display in the PE
  Client Statistics Details window when group scope is selected.
  

Problem conclusion

• 1. The code has been corrected and the PE Server subtask trace
  has been extended to report storage allocations if the PE
  Server subtask trace level 64 is set.
  2. All provided IFCID 2 data from all contributing members of
