How to configure nginx to hang but not crash?
I set it up so that an error 500, 501, 502, 503, 504 pops up with a load of 300 users, although the percentage is only a third loaded, and the load average does not exceed 0.6
Let it be better for the pages on the site to open for 3 seconds than it will throw out users

Answer 1

Increase the timeouts you need and the number of ngix workers
