Out of the blue, my Discourse instance (docker installed) is returning Bad Gateway errors at intervals. The container is still running, but I need to manually stop and start the app to get things going again. Then it seems fine … until this occurs again sometime shortly later. I’m unsure of the appropriate log location for more info. Where should I start? Thanks very much!

Are you running out of RAM? What does `free -h` say?

What do you see in `/var/discourse/shared/standalone/log/rails/production.log` (I think I typed it right, but if not, you’ll have to adjust). And `/var/discourse/shared/standalone/log/var_log/nginx/..something...`

I’ll check the next time this happens. Thanks! Right now less than 50% RAM in use.

Probably not RAM, then. You can look at the logs now.

The logs look OK. Nothing obvious anyway. Even when it’s up, it’s been very sluggish. Often takes a long time to respond, long enough that it timeouts for users (or even me, locally). Really strange since that box has been stable for a long time and little changes on it other than routine Ubuntu updates (18.04).
