Hi I have a nodejs websocket app using microWS (also happens with websockets/ws), once I connect more than 2k customers I start getting 502 errors for each client. While I'm getting these errors I  connect to the vm using ssh and in the error log of nginx I see the error line "4096 worker_connections are not enough" for each client.

Running the following commands via ssh I was able to solve the problem (just update the worker_connections at nginx):
sed  's/worker_connections [0-9]*/worker_connections 40000/g' /tmp/nginx/nginx.conf  
docker exec nginx_proxy cp /tmp/nginx/nginx.conf /etc/nginx/nginx.conf &&  docker exec nginx_proxy nginx -s reload

However I couldn't find anything in the app.yml, neither could do this using a custom Dockerfile. Is it posible to update this limit at all or too update the number of workers?,because I'm not even near hitting 70 % cpu neither the memory grows too much due to microWS library.

I saw this issue https://issuetracker.google.com/38243437 which is related, but since we are using websocket the connection will be persistent and a server will not be able to support more than ~ 2000 connections which for me it seems really low in scalability terms.

Thanks
