Can you share the version of container agent you are using? It should be available in the “Self-hosted Runners” inventory in the UI or if there is a build link, in the “Task Lifecycle” step output.

The first step to diagnose would be to try to upgrade the helm chart and see if this issue still occurs with the latest version. [https://circleci.com/docs/runner-faqs#updates-to-container-agent-functionality](https://circleci.com/docs/runner-faqs#updates-to-container-agent-functionality)
