Experimental Dashboard feature causes memory leak in rancher server and cattle-cluster-agent processes in Rancher v2.4.0 - v2.4.2

This document (000020112) is provided subject to the disclaimer at the end of this document.



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:

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


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