Progressively worse 500 errors

bug
1

I’m on a fresh docker install about a week old upgraded to the latest docker container. After a day or two of operation, Discourse starts throwing 500 errors on nearly any sort of action. Thread views, attempts to access the admin panel, anything. The error log accessible by the admin panel has very little in it-- this is happening for lots of people simultaneously on nearly any action but there’s nothing showing up in the error log correlated to the times of these page views. I see a few errors there, mostly this: “TypeError: e.get is not a function” but I doubt entirely these are correlated to the problem at hand.

This gets progressively worse after it begins happening until everything is throwing an error 500 a hundred percent of the time. I currently fix it by doing:
./launcher stop app
./launcher start app

What can I do to diagnose this?

Can you post the result of the following commands.:

  • df -h
  • df -i
  • free -m

When the server is giving 500 a top would be nice too.

Looks like there isn’t any swap. See the topic at #howto

EDIT: Please add the results from those commands as well:

  • docker --info
  • docker --version
