Thank you for your contribution @harshitkr12! We will review the pull request and get back to you soon.

Thank you! I am approving the pull request, it looks good to me. I'd like @LarryOsterman to review before merging.

@LarryOsterman, if you will be doing the next release (it is probably January 8, unless @ronniegeraghty says it is a week after), please make sure that the changelog has an entry for this fix, as well as the acknowledgements section + credit after the fix line, similar to the other fixes that we've taken.
The upcoming release should probably be the beta.

OR, I think we can wait for the week of Jan 12th - it is still going to be a release week, and then I can make the release myself. I suggest we do that.

But just in case, here is the hange that we'll need for the CHANGELOG.md in core:

# Release History

## 1.17.0-beta.1 (2026-01-08)

### Bugs Fixed

- [[#6817]] Fix CPU spinning when curl_easy_send returns 0 bytes on SSL socket writes. (A community contribution, courtesy of _[[harshitkr12](https://github.com/harshitkr12)](https://github.com/harshitkr12)_)

### Acknowledgments

Thank you to our developer community members who helped to make Azure Core better with their contributions to this release:

- harshitkr12 _([GitHub](https://github.com/harshitkr12))_

I am going to follow up with Rubrik in the issue letting them know how they can start consuming it right away, if they need it.

/azp run cpp - core

Live tests are green.

@antkmsft @RickWinter Are we good to merge this PR? @agabhin has explained why we are using sleep_for instead of yield here - #6890 (comment).
