With the experimental Dashboard feature enabled in Rancher v2.4.0 through v2.4.2, the rancher server and cattle-cluster-agent processes will leak memory. As a result the memory usage of these Pods will grow over time, until they restart due to an Out of Memory (OOM) condition.
- A Rancher install with either v2.4.0 or v2.4.2
Disable the experimental Dashboard feature within the Rancher UI:
- Navigate to the Global View -> Settings -> Feature Flags.
- Click the elipses for the
dashboardentry and click
Upgrade to a newer version of Rancher v2.4.3+.
