Readiness probe failed

Hello,

We regularly have pods which are in error and which do not restart correctly. The only solution remains to delete the pod.

Warning Unhealthy 37m (x29 over 39h) kubelet Readiness probe failed: Get "http://10.200.6.5:8002/ready": context deadline exceeded (Client.Timeout exceeded while awaiting headers) Warning Unhealthy 32m (x12 over 39h) kubelet Liveness probe failed: Get "http://10.200.6.5:8090/healthz": context deadline exceeded (Client.Timeout exceeded while awaiting headers) Warning Unhealthy 2m1s (x1396 over 94m) kubelet Readiness probe failed: HTTP probe failed with statuscode: 503

The issue happen more and more, recreating the pod can't be a solution. How can I fix the issue ? Is there any logs I can check to have more information about what happen ?

Kubernetes version is 1.24.14 Contour version is 1.23.6

The same issue was already present with previous version of kubernetes and contour.

Regards.

I experience this issue on the envoy pods, too. Usually the envoy /ready endpoint returns a valid response within < 100ms, but sometimes its response time takes over 5 seconds. I am not sure why.
