  *                  Server V6.1.0                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: Sockets may be left open on failed      *
  *                      outgoing connections, resulting in      *
  *                      too many open files in system errors.   *

  * RECOMMENDATION:                                              *
  ****************************************************************
  If a socket close() is issued on a outgoing connection and the
  close is not successful the socket will not be cleared up
  for an outgoing connection.
  

Problem conclusion

• The close retry logic is performed so that if a close() is not
  successful the close() will be redriven after a short interval.
