### Documentation Insights
There are several references to handling Kubernetes-related issues in the Prefect documentation, such as orchestrating Kubernetes pods and setting up Prefect Cloud connections. However, there isn't a specific mention of handling stuck flow runs due to lost pods.

### GitHub Insights
There is a relevant GitHub issue titled
"An error occurred while monitoring Kubernetes flow run" where the agent loses track of the pod, and the flow run becomes stuck in the running state. The details mirror the problem you described.
- Issue Details:
GitHub Issue #8243
### Recommendations
1.
Monitor Pods Status: Implement a custom monitoring system to regularly check the status of your Kubernetes pods. If a pod is found missing, handle it programmatically.
2.
Prefect API: Use the
prefect
CLI or Prefect's API to query the status of your flow runs and mark them as failed if the corresponding pod is no longer available.
3.
Error Handling: Adapt the error handling mechanism in your flow to catch such events and terminate or retry gracefully.
4.
Retry Logic: Implement retry logic within the Prefect flow to respond to such failures.
### Next Steps
Consider creating a watchdog service that interfaces with both your Kubernetes cluster and Prefect API to identify and clean up such orphaned flow runs. If you encounter persistent issues, opening a more detailed support request with Prefect might be necessary.
