## Troubleshooting

{{% thirdparty-content %}}

If updating the pod spec returns an `invalid spec` error, ensure that the feature is enabled on all of the following components:

- API server
- Controller manager
- Scheduler
- All kubelets (across all worker nodes, and all control plane nodes if your cluster has them)


If the updated spec is accepted, but pods are stuck in the `InProgress` state or otherwise unable to run,
ensure that your environment is configured to use a [container runtime](/docs/setup/production-environment/container-runtimes/)
that supports in-place changes to container resources. For example:

- [containerd](https://containerd.io/) (version 1.6.9 or greater)
- [cri-o](https://cri-o.io/) (any version)
