Why Ubuntu 22.04 Upgrade Crashes Java Apps on Kubernetes: The cgroup v2 Trap

Upgrading a Kubernetes cluster from CentOS 7.9 to Ubuntu 22.04 caused Java pods to crash with OOMKilled errors; increasing memory limits only hid the issue, and the root cause was cgroup v2 making the JVM misinterpret its resource limits, resulting in excessive threads and heap sizes. The article advises upgrading to a JVM that supports cgroup v2 or reverting the node to cgroup v1.
