  ****************************************************************
  PH27933 fixed ABEND04E RC00E70005 DSNXESX4 P404 caused by
  Db2 under-calculated the storage needed for local control
  blocks of a large and complex SQL statement with REOPT(ONCE)
  and multiple index access and thousands of predicates.
  But PH27933's fix miscalculated local control block's size,
  causing DSNXESX4 P404 being incorrectly issued for SQL
  statement that should not receive ABEND04E RC00E70005.
  

Problem conclusion

• The Db2 code has been changed to correctly calculate the size
  of local control blocks, no more incorrect
  ABEND04E RC00E70005 DSNXESX4 P404 being issued.
