Opened: May 01, 2025 Severity: 3-Major
Over time, controller memory utilization steadily increases due to growth in OpenShift 3.11 control-plane processes (openshift start master api and openshift start master controllers). Initially, the Chassis and pods generally remain operational. However, prolonged uptime can lead to elevated load, reduced performance margin, and eventual need for controller reboot to reclaim memory.
Steady rise in the memory usage of the controller and higher sustained system load over time.
The issue occurs during normal long-running operation on systems using embedded OpenShift 3.11 control-plane components. As uptime increases (days to weeks), the openshift start master api and openshift start master controllers processes exhibit gradual RSS memory growth.
Perform a controller reboot to temporarily reclaim memory.
