v0.1.0-rc3 seems to be unstable a few minutes after startup

[motoki317]

Hello, thank you for this developing this project!

I was trying to use the new v0.1.0-rc3 version via the helm chart, and it seems to work right after the startup:

2024-10-11T07:40:28.057917Z  INFO admission{object_ref=Pod.v1./common-ingress-nginx-controller-7c669574db-vnknh.ingress-nginx operation=Delete request_id=252073096}: pod_graceful_drain::webhooks::report: action="DelayDeletion" reason="Drain" note="Deletion is delayed, and the pod is isolated.

But quickly degrades and the webhook server seems to throw only errors a few minutes after the pod-graceful-drain container startup.
There are WARN and ERROR lines in logs:

I know this version is still in release candidate, so I'll use the latest stable version (v0.0.8) for now.

Thank you in advance!
