TL;DR

The issue of duplicated output may be related to the errors encountered, particularly the MaxFileReadTokenExceededError, which suggests that the file content exceeds the maximum allowed tokens, potentially causing the duplication.

Guidance

• Review the error logs to understand the sequence of events leading to the duplicated output, focusing on the MaxFileReadTokenExceededError and how it might influence the output.
• Consider implementing pagination or limiting the file read tokens to prevent the MaxFileReadTokenExceededError, potentially resolving the duplication issue.
• Investigate if the Lock acquisition failed error is related to the multi-process scenario and if it could be contributing to the duplicated output by causing processes to overlap or repeat tasks.
• Check if the FileTooLargeError is relevant to the issue at hand, as it might indicate a need to handle large files differently to avoid errors that could lead to duplicated output.

Example

No specific code example can be provided without more context on how the output is generated, but adjusting file reading to use offset and limit parameters as suggested by the FileTooLargeError could look something like adjusting a function call to include these parameters, though the exact implementation depends on the actual codebase.

Notes

The provided errors suggest issues with file handling and token limits, which might not directly cause duplicated output but could contribute to an unstable environment where such issues arise. The Lock acquisition failed error hints at potential concurrency issues.

Recommendation

Apply a workaround by adjusting file reading parameters (like offset and limit) to stay within the token limits and handle large files more efficiently, as directly implied by the error messages. This approach is chosen because it directly addresses errors mentioned in the issue and could mitigate the conditions leading to duplicated output.
