Deployed server with NGINX -> uWSGI -> Django stack on OC Debian. When the number of requests increases to 150 requests per second, a 502 Bad Gateway error occurs. There is no load on the iron. Tried various configurations of uWSGI workers and tweaking the Linux networking stack, but all to no avail.

It looks like your backend is responding too slowly. Either optimize or increase the number of workers.
