Description Divyam Pateriya 2022-02-20 09:09:33 UTC 
Description of problem:

Pods are stuck in a container-creating state due to kuryr-cni not being able to assign IP to the Pod.

How reproducible:

Happens quite frequently on a specific namespace where more than 300 pods are running.


Steps to Reproduce:

2. Create a project and deploy 300+ pods within the namespace.

3. Try to rollout deployment/restart the app pods.

Pods should run just fine.

I'm marking this as a duplicate as there's a fix in 4.8.26 that greatly improves such situations. Please reopen if this proves to include different issues.
