I’m working on a fairly high-volume site (>150K pageviews/day). I’m getting some 429 errors, at least mostly on the message bus. I earlier had some issues due to a misconfiguration of
set_real_ip_from, but that’s resolved. I also removed (perhaps temporarily?) the rate limiting template.
I’m still seeing about .5 429 errors per second.
I’ve got 5 unicorn workers with a 2 core/4 thread CPU. 16GB ram. Postgres is on a separate host. CPUs remain >50% idle
I removed the rate limiting template and raised unicorn workers to 5 at about 8:20.
