I'm not quite sure how to reproduce this, but I've observed this panic in the agent.

Hey @julianvmodesto, sorry to see that. We have not received similar reports with such a stack trace as far as I know. Could you reach out to support@datadoghq.com ? It would be much more efficient to further investigate. We will post an update here as we make progress as well. Ideally, could you share the details on how you install the agent and the environment as well as the logs via a flare command ?

Thanks!
