What is exit code 14 in MongoDB?

In MongoDB, exit code 14 indicates that the application has encountered an unrecoverable error, such as an uncaught exception or signal, leading to an abrupt termination without a clean shutdown.

Common Causes

• Uncaught Exceptions: Errors in the application code that aren't properly handled.
• Uncaught Signals: Unexpected system signals that disrupt normal operations.
• Configuration Issues: Misconfigurations, especially related to file paths or permissions.
• Resource Limitations: Insufficient system resources like memory or disk space.

Troubleshooting Steps

1. Review Logs: Check MongoDB logs for detailed error messages to identify the root cause.
2. Verify Configurations: Ensure all configurations, such as file paths and permissions, are correctly set.
3. Check System Resources: Confirm that the system has adequate resources to support MongoDB operations.
4. Update Software: Make sure MongoDB and its dependencies are up to date to prevent known issues.

By systematically addressing these areas, you can resolve the issues leading to exit code 14 and maintain stable MongoDB operations.
