How to debug occasional 502 errors with DO + Nginx + Puma?

1. puma-daemon

   1 1 39 4.0 Ruby

   Puma (starting version 5) removed automatic demonization from the gem itself. This functionality was extracted to this gem, which supports Puma v5 and v6.

   

   What I have: * $6 DO droplet (1GB memory, 1vCPU) * Puma (min threads: 5, max threads: 5, workers: 2 - all default) + puma-daemon * Nginx (mostly default except proxy_pass http://localhost:3000;) * PostgreSQL service (pool: 5 - default)

2. InfluxDB
