don't use runserver for production ever.

read the django documentation: https://docs.djangoproject.com/en/1.10/howto/deployment/

after that I suggest using nginx with uwsgi

it is also worth reading uwsgi documentation, there are a lot of options you can tweak

nginx also has some options you can tweak

I'm building a Django server for data collection. However, the program seems not capable when the sensing network expands. As time goes on, the program doesn't even enter the code piece and report broken pipe/connection reset by peer/too many open files errors:

I checked the open files and it seems like the socket files are never closed. The list is full of items like the followings:

Any ideas? Let me know if you need any further information.
