Accept Errors

[Olaf van der Spek <olafvdspek@…>]

If an error occurs, the server stops accepting new connections. I think this was reported before (for another example) and I think other examples also suffer from it.

boost_asio/example/local/stream_server.cpp

  void handle_accept(session_ptr new_session,
      const boost::system::error_code& error)
  {
    if (!error)
    {
      new_session->start();
      new_session.reset(new session(io_service_));
      acceptor_.async_accept(new_session->socket(),
          boost::bind(&server::handle_accept, this, new_session,
            boost::asio::placeholders::error));
    }
  }
