What is the maximum nginx worker_connections I can set for my droplet?
I have a NodeJS API running on a 4GB Memory and 2 Core CPU Standard Droplets. The API has real time functionalities using Socket.io and is serving around 500 concurrent users.
Lately I noticed that the API sometimes stop handling any requests for like 5 - 10 seconds and then continues to work.
When I checked Nginx error logs I found this alert occurring a lot :-
[alert] 7193#7193: 768 worker_connections are not enough
Could this be the issue making the API miss some requests?
And how do I know what is the maximum worker_connections I can set? Currently it is set to 768
