-!!! note
-    There is a bug in the current stable release of gunicorn (v21.2.0) where automatic restarts of the worker processes can result in 502 errors under heavy load. (See [gunicorn bug #3038](https://github.com/benoitc/gunicorn/issues/3038) for more detail.) Users who encounter this issue may opt to downgrade to an earlier, unaffected release of gunicorn (`pip install gunicorn==20.1.0`). Note, however, that this earlier release does not officially support Python 3.11.
