What you expected to happen:

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• Kubernetes version (use kubectl version):
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others: Kuberentes: v1.11.2

When I’m testing nvidia-device-plugin, and trigger it return error: invalid allocation request: unknown device

https://github.com/NVIDIA/k8s-device-plugin/blob/v1.11/server.go#L165

It retries continuously because it’s UnexpectedAdmissionError.

kubectl get po | grep UnexpectedAdmissionError | wc -l
1181

I suggest to make it retry with an with an exponential delay(10s, 20s, 40s …).
