  * PROBLEM DESCRIPTION: DFHWB0732 when an SSL TCPIP connection  *
  *                      is unexpectedly closed during handshake *

  ****************************************************************
  A request is received on an HTTP SSL TCP/IP service. The
  requestor immediately closes the connection before the SSL
  handshake can complete. The receive issued by the SSL handshake
  process gets a reason of connection_closed with a
  gsk_return_code of gsk_err_socket_closed. This reason code is
  not handled so the default handshake_error is returned. This in
  turn causes message DFHWB0732 to be issued.

Problem conclusion

• DFHSOSE has been changed in routine sose_call_secure_soc_init
  to check for reason code sose_connection_closed with a
  sose_gsk_return_code of gsk_err_socket_closed and if found,
  return that instead of the default handshake_error. This
  will eliminate the DFHWB0732 message.
