In the Kubernetes documentation, it says "the cgroup’s processes are throttled and put under heavy reclaim pressure". But what does "put under heavy reclaim pressure" mean from the perspective of Kubernetes and CGroup V2?

  • **memory.high** specifies the memory usage throttle limit. This is the main mechanism to control a cgroup's memory use. If cgroups memory use goes over the high boundary specified here, the cgroups processes are throttled and put under heavy reclaim pressure.
