Operating System

k8s

Docker Selenium version (image tag)

4.26.0-20241101

Selenium Grid chart version (chart version)

0.37.1

Start with the EventBusCommand entry point and the java.nio and ZeroMQ stack trace in the report, using the 4.26.0-20241101 image and 0.37.1 Helm chart. Reproduce the out-of-memory failure in Kubernetes and determine whether it is caused by the deployment configuration or the event bus. Done means the cause is confirmed and a tested fix or configuration change is identified.
