Process killed because out of memory

[viktoriaas]

What happened:
When I try to create multiple PVCs at once, the process inside NFS controller is killed because memory cgroup is out of memory

[1160550.652403] Memory cgroup out of memory: Killed process 2801203 (mount.nfs) total-vm:156432kB, anon-rss:71132kB, file-rss:4296kB, shmem-rss:0kB, UID:0

What you expected to happen:
PVCs are created.
How to reproduce it:
I think it is sufficient to request more resources than this file specifies (around lines 44, 64, 90). It already happend and was resolved only by manually rewriting amount of limits Deployment can request (I put 10x more)
Anything else we need to know?:

Environment:

• CSI Driver version: latest master
• Kubernetes version (use kubectl version): v1.19.3
• OS (e.g. from /etc/os-release): CentOS Linux 8
• Kernel (e.g. uname -a): Linux 4.18.0-240.10.1.el8_3.x86_64
• Install tools:
• Others:

so double the csi-provisoner memory limit would work? 1000Mi is too much, would you try double the memory limit next time? thanks.

csi-driver-nfs/charts/latest/csi-driver-nfs/templates/csi-nfs-controller.yaml

Lines 44 to 47 in 87e6ba8

	resources:
	limits:
	cpu: 100m
	memory: 100Mi

Doubling would work, container is requesting at least 156Mi so 200Mi should be fine.
