Why do you need to close the acceptor? Can't you continue accepting incoming
connections with the same acceptor?
Why do you need to close the socket? You said that the client already
disconnected, so your server socket is closed anyway.
Anyway, if your asio_socketPtr is a server socket that accepts an incoming
connection, then you have to pass it to the acceptor's async_accept/accept
member functions - the acceptor will "open" the socket.
