Memory requirements/leak?

[kuhnroyal]

I updated form version 4 to 8.0.1, using via Kubernetes.
The pod previously had 640Mb memory limit and seemed to be fine.
Now it keeps being killed with out of memory, I gave it 1200Mb but that didn't help.

What is the expected memory consumption?

What are you using as db and storage?

[kuhnroyal]

I am using S3/MiniO and Postgres

Does it always use that much memory (eg directly after restart) or does it get more over time?

[kuhnroyal]

It was killed 07:15 when there was the ~2GB memory usage.

So it doesn't always use that much memory and it goes back down.
I have some 2+GB cache up/downloads and it seems that they are in memory.

This seems to be the build during which it happened.
