If the node Authentik worker ends up getting assigned to, happens to have less than optimal amount of RAM, k8s cannot know to not schedule it there without the request of resources specified so what happen is system OOM.

Node is an Raspberry Pi 4, with 2GB of RAM even tho there's others that have more.
