3.2. Performance and scaling
RHEL 9 compute nodes cause severe database workload performance degradation

Jira:KATA-2247
Excessive metric reporting causes Prometheus pods to fail
Previously, the kata_shim_netdev metric reported an excessively large volume of metrics, which caused Prometheus pods to fail with out of memory errors. In the current release, the issue has been fixed.
controller-manager pod fails with out of memory errors
Previously, when the OpenShift sandboxed containers Operator was deployed on a single-node, bare-metal cluster running OpenShift Container Platform 4.14.12, the controller-manager pod failed with out of memory errors. In the current release, the issue has been fixed by increasing the pod’s resources.
