This relates to tornado_main.py. http://localhost:8080/hello-tornado works OK but
http://localhost:8080/hello-django returns a 500: Internal Server Error

Hello,

def main():
    tornado.options.parse_command_line()
    wsgi_app = tornado.wsgi.WSGIContainer(
        django.core.handlers.wsgi.WSGIHandler())

    application = Application([(r'/websocket/', planet_socket.WsDate),
                               ('.*', FallbackHandler, dict(fallback=wsgi_app)),
                               ],
                              **settings)

    print options.port
    server = tornado.httpserver.HTTPServer(application)
    server.listen(options.port)
    tornado.ioloop.IOLoop.current().start()

if __name__ == '__main__':
    main()

When we are running the project as above, We take the problems as below.

When a request starts(such as showing 10K records to the screen) all other requests are waiting until the first request is completed.
Requests which are running on Web Socket are waiting for first request's completion.
When a user starts the first request then all other users are waiting the first request's completion.
Sample Project is here. How Can We fix this problems..

Do you have any idea ?

Thanks...

Hi, is there any way to run this (tornado_main.py) along with django builtin webserver, not just inside wsgi app, please?

this example is created 4 years ago and dont working now please refresh.

This demo is simple and useful, but because of the issue, --port=XXXX won't be effective.

Hi bdarnell,
It is very usefull repo for me. I am runing tornado server and it is working fine, But when I am using gunicorn i'm facing some issues. Can you please look at this error,
