  ****************************************************************
  CEMT SET CONNECTION RELEASED was issued against an LU6.2
  syncpoint level 1 autoinstalled connection on a CICS region that
  was registered as a z/OS Communications Server generic resource.
  When the last session for the connection was terminated, DFHZCLS
  checked flag TCSE_DELETE_SCHEDULED is not already set and then
  set it on before initiating transaction CATD to delete the
  connection. The CATD task was suspended on the load for DFHZATD.
  DFHZCLS issued message DFHZC3462, triggering a user DFHZNEP
  program that invoked EXEC CICS SET CONNECTION OUTSERVICE
  followed by EXEC CICS SET CONNECTION ENDAFFINITY.
  DFHZGCH attempted to delete the autoinstalled connection as part
  of ENDAFFINITY processing but did not check
  TCSE_DELETE_SCHEDULED before initiating a second CATD
  transaction.
  The first CATD task completed successfully and the second failed
  because the connection had already been deleted.
  

Problem conclusion

• DFHZGCH has been changed to test tcse_delete_scheduled and,
  if it is already set on, it bypasses the attempt to delete the
  autoinstalled connection and a second CATD transaction is not
  initiated.
