Blob Storage SDK hits timeout issue periodically, no indication as to why

[Petermarcu]

Reported by Nicolas Garfinkel (@Garfinkel). Nicolas Garfinkel (@Garfinkel) if you could share more details of the script you used, that would be helpful.

I ran a Python script which uploads a ~30-50mb GZIP file to Azure Blob Storage through the Python SDK (v 12.3.1) using Python 3.7.5 and 3.7.7. The error I receive indicates a timeout issue with no indication why other than "server response error".

We should better indicate when issues are transient / potentially an Azure issue as opposed to a user issue.

Region = us east

... 1_CallAPI.venv\lib\site-packages\azure\core\pipeline\transport_requests_basic.py", line 284, in send

raise error

azure.core.exceptions.ServiceResponseError: ('Connection aborted.', timeout('The write operation timed out'))

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc xgithubtriage.

Hi Nicolas Garfinkel (@Garfinkel)

It could because of the max_single_put_size, sometime the first put blob request cannot finish within the specified/default timeout value, set max_single_put_size to a smaller value like 20*1024*1024 could be a workaround to fix the problem. We will investigate offline and see how we should modify the SDK.

We have this same issue, weird part is that it only happens on certain occasions and on certain laptops.
