Analysis

• Consistent Location: All events occurred in the engine/task_worker.py file, specifically in the run method of the engine.task_worker.
• Frequent Occurrences: The issue has been recurring over a span of nearly two months, indicating a persistent problem.
• Potential Cause: Given that the error is a ConnectionError with the message "Connection closed by server," it suggests that the task worker is attempting to connect to a server that intermittently closes the connection.

Next Steps

1. Investigate the run Method: Review the run method in the engine/task_worker.py file to identify any potential issues with the connection logic.
2. Check Server Logs: If possible, check the logs of the server to which the task worker is connecting to understand why the connection is being closed.
3. Implement Retry Logic: Consider implementing retry logic with exponential backoff in the run method to handle intermittent connection issues more gracefully.
