[asio] "bad_descriptor" error on async_send_to + socket.close Hi, I am trying to close a UDP socket on which an async_send_to operation is running. The handler is like this: void Sender::handleSend(error_code const & e, size_t bt) { this_thread::sleep(posix_time::seconds(1)); socket.async_send_to(buffer, remoteEndpoint, bind(&Sender::handleSend, this, placeholders::error, placeholders::bytes_transferred)); } The sender itself is fine. But on some special occasions I have to close the socket. I do it like this: void Sender::do_close() { socket.close(); } void close() { socket.get_io_service().post( bind(&Sender::do_close, this)); } When close() is called, the async handler yields a "bad_descriptor" error. I would expect an "operation_aborted" error as stated in the documentation. For async_receive, everything is fine and works as expected. What am i getting wrong? Greetings, B.
