  PROBLEM SUMMARY:
  When DB2 9 Dynamic Statement Caches contain more than 32k
  statement entries, the count field for the repeating data
  section in the retrieved IFCID 316 overflows.
  For values between 32k and 64k the parser in the PE Server
  subtask interprets the field as a negative count and therefore
  no data are returned.
  If more than 64k statement entries exist, the overflow results
  in a value below 32k and therefore the PE Server subtask only
  parses this amount of data.
  
  
  PROBLEM CONCLUSION:
  The parsing algorithm for IFCID QW0316 has been changed to be
  independent of the count field.
  

Problem conclusion

• The parsing algorithm for IFCID QW0316 has been changed to be
  independent of the count field.
