Is there a way to give certain processes priority if memory gets bogged down?

E.g., I'd like the ssh server to always have top priority on a headless device, so if some other processes are bogging things down, I can still "get in" to fix things.

On my raspberrypi 4 running umbrel, it seems like things get bogged down and ssh server is the first thing to go. I can ping the device just fine--but ssh connection just gets refused.

...or is this "not how any of this works"?

If you run the other processes in containers you can limit how much memory they can access.

Most people use docker for this. https://docs.docker.com/engine/containers/resource_constraints/

I think everything on the umbrel is in a container...but ty might look into this...

I wonder if you can identify which cgroup(s) the containers run in and limit the memory of the containers that are consuming toouch memory.
