Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users of IBM HTTP Server                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: Graceful shutdown of child process      *
  *                      triggered by some conditions during     *
  *                      client accept()                         *
  ****************************************************************
  * RECOMMENDATION:  Apply this fix                              *
  ****************************************************************
  A "AcceptErrorsNonFatal" directive was added which alters the
  accept() failure processing so that ECONNREFUSED,
  ECONNABORTED, ECONNRESET during client accept() won't trigger
  graceful shutdown of the child process.
  

Problem conclusion

• Added "AcceptErrorsNonFatal" to allow ECONNREFUSED,
  ECONNABORTED, and ECONNRESET during the client accept() to not
  trigger graceful shutdown of the child process.  Default
  behavior is still to exit.
  
  This fix is targeted for IBM HTTP Server fix packs:
  - 8.0.0.15
  - 8.5.5.14
  - 9.0.0.8
