"The job instance became unhealthy and the job was restarted" - what does it mean and how to deal with it?

 In SimScale, the message "The job instance became unhealthy and the job was restarted" indicates an issue with the cloud server running your simulation, not your simulation setup itself.

Here's a breakdown:

• Unhealthy Job Instance: The cloud server where your simulation was executing encountered a problem. This could be due to various reasons on SimScale's backend and not necessarily related to your simulation files.
• Job Restarted: SimScale automatically detects the unhealthy server and restarts your simulation on a different server, ensuring it continues running.

There's usually no need for you to take any action. The restart shouldn't affect your core hours (the compute time you pay for on SimScale).

However, if the job restarts multiple times, it's recommended to report it to SimScale's platform team for further investigation.

👽 What Can I Do???

Since the "The job instance became unhealthy and the job was restarted" error message in SimScale indicates an issue with the cloud server rather than your simulation setup, there's usually no action you need to take. SimScale automatically restarts the job on a different server to ensure it continues running.

Here are the recommended steps:

1. Monitor the Job: Keep an eye on the job status after the restart. If it completes successfully without further issues, you can proceed as usual with your analysis.

2. Repeated Restarts: If the job restarts multiple times, it's an indication of a persistent problem with the simulation setup or the cloud servers. In this case:

   a. Report to SimScale: Contact SimScale's support team or platform team through their official channels. They can investigate the underlying cause and provide further assistance.

   b. Provide Details: When reporting the issue, include relevant information like the job ID, simulation setup details, and any error messages you encounter. This will help the support team identify the root cause quickly.

   c. Consider Rerunning: Once the SimScale team has addressed the issue, you can try rerunning the simulation. If it still restarts, there might be a problem with your simulation setup, and you may need to consult SimScale's documentation or community forums for troubleshooting.

Remember, SimScale is continuously working to improve their platform stability, and these server-side issues are relatively rare. By following these steps, you can effectively handle the situation and ensure your simulations run smoothly.
