Enable debug logging on Nostream by setting the DEBUG env var to `worker:*`
Then go to your invoice page and inspect the logs.

Wow, this is a dense log! Thanks, I'll report back!
Oh no, this is embarrassing: I think I've finally found the problem and it has nothing to do with nostream. 🙈 It seems the main reason of my outages have been too low limits in my NGINX configuration (worker_connections & worker_rlimit_nofile). But thanks to your help I have improved swap and memory efficiency on the way. 🤙 I am 99% sure the problem is gone now. I'll wait some days and then document my findings in the issue and close it. Thanks for your help!
Glad you were able to solve it! 😎 If you get any more issues let me know.
That would be useful to mention in the README
