Hey @nikitadom, Mountpoint currently tries to use 512 MiB memory by default, by looking at the logs it seems like it has less than minimum memory available – which might be causing OOM. Would you be able to increase Mountpoint's memory to a higher limit?

You might be also running into awslabs/mountpoint-s3-csi-driver#82, the CSI Driver currently spawns Mountpoint in systemd context and consumes systemd resources rather than Kubernetes/container resources.

Where should I increase the memory?
