  ****************************************************************
  An ABEND04E RC00E20016 may occur in module DSNSVSTK after
  many CICS calls to DB2 SIGNON are rejected by the DB2 Signon
  authorization exit.
  Each CICS call to DB2 SIGNON receives a RC00F30058
  which means the userid is rejected by the authorization
  exit.  CICS makes a TERMINATE call to to DB2.
  That TERMINATE call causes DSN3ID80 to set RC00F30054
  and DSN3ID80 does not clean up its DB2 stack entry.
  

Problem conclusion

• Module DSN3ID80 has been updated to avoid the ABEND04E
  RC00E20016 and ABEND878 in the application address space.
