We just updated from 3.0.6 to 3.1.2 and I’m seeing many 503 errors at mainly 3 points:

- Many avatars fail to load
- Image uploads only works sometimes
- Also seeing many errors for `topics/timings`

I have looked at the server logs, and most 503 don’t even show on `production.log`, but nginx is full of them. Thinking it could be nginx rate limiting, I tried not using the `templates/web.ratelimited.template.yml` but it didn’t seem to help. I’m still seeing a high amount of requests answered with 503, mostly `user_avatars/show` and from what I gather, `production.log` doesn’t seem to see them at all.

Don’t notice anything wrong in sidekiq. However, `/logs` did have errors with,

```plaintext
'hijack user_avatars show ' is still running after 90 seconds on db default, this process may need to be restarted!

```

but these were a couple of hours ago and I’ve rebuilt the instance couple of times since then and they haven’t shown again.

This instance is using SSO, so the avatars (url) comes from there. We are using S3 for images.

I’m a bit puzzled to what is causing this and I’m out of ideas.

Any clues where/what to look into?
