Hi,
I am having two major issues with the Paperless-ngx app.
The first one deals with Gotenberg. Processing of - in my example - .eml and .html files fails with 500 Internal Server Error.
On closer inspection of the logs, I can see this error relating to permissions:

It seems the chromium binary wants to write to /root/.local/share/applications where it has no permissions?
The second issue comes from the fact that the Paperless-ngx app is generating an enormous amount of logs, even under normal conditions.
I am pretty sure that this is why my Paperless-ngx instance is causing extreme CPU load (completely maxed) as well.
I'm not able to interpret the cause of the logs, but it looks like something related to Celery Scheduling or Redis is out of whack.
Here are things I have already tried:
- Using the Cloudron Panel, move Paperless-ngx data, from a volume I used before, to the default location in container (no effect)
- Delete /app/code and let container recreate it (no effect)
- Use
cURLto send a simple test HTML file to Gotenberg to see if it can process it (same 500 Internal Server Error with accompanying logs)
I should note that I recently performed a "backup and restore" as described in your documentation, which has been uneventful with the exception of the above-stated issues with Paperless.
However, I don't know if they are directly related.
I have linked the relevant part of the application log, where you can see both the issues with Gotenberg as well as the issue of very high log volume:
