- Kubelet now detects terminal CSI volume mount failures due to exceeded attachment limits on the node and marks the stateful pod as Failed, allowing its controller to recreate it. This prevents pods from getting stuck indefinitely in the `ContainerCreating` state. ([...

pods, memory can not be fully reserved, and the page cache is at risk of being recycled. For `Burstable` pods, overcommitting memory (setting `request` less than `limit` ) could increase the risk of a container being killed when the Linux kernel detects an out of memory condition.

As an alpha feature, Kubernetes v1.22 can use the cgroups v2 API to control memory allocation and isolation. This feature is designed to improve workload and node availability when there is contention for memory...

* **[beta]** Node Problem Detector is beta (v0.3.0) now. New
  features added into node-problem-detector:v0.3.0:
  - Add support for journald.
  - The ability to monitor any system daemon logs. Previously only kernel
    logs were supported.
