[botocore INfO log] how to deal with htttpchecksum.py line 487

[jxing98]

Hi team,

Background
I am upgrading a program from py3.8 -> py3.9 and I get same error with #3113 and I tried workaround following #3113 (comment). After disable threading the error is disappear.

Issue
But I get https://github.com/boto/botocore/blob/develop/botocore/httpchecksum.py#L487 logging every time I tried to download a file, my code is like s3.download_file(bucket_name, object_name, file_name, Config=TransferConfig(use_threads=False))

Question

• Does this log line means my file completeness is not guarantee?
• If so, could you please suggest a way to solve it

Thanks!
