Description
Hello,
Recently, we upgraded to Django 4.2.16. One of the servers crashed with the below error:

The error seems related to https://github.com/python/cpython/issues/124170 and https://github.com/django/django/commit/bf4888d317ba4506d091eeac6e8b4f1fcc731199.
Below are the versions we use:
- Django: 4.2.16
- Python: 3.8.10
- Gunicorn: 22.0.0
Thank you!

Thank you for the quick response. And sorry if it's the wrong place to report the issue.
