Issue

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.

Pre-requisites

  • A Rancher install with either v2.4.0 or v2.4.2

Workaround

Disable the experimental Dashboard feature within the Rancher UI:

  1. Navigate to the Global View -> Settings -> Feature Flags.
  2. Click the elipses for the dashboard entry and click Deactivate.

Resolution

Upgrade to a newer version of Rancher v2.4.3+.
