Update: I just tried it again with
- Windows 10 Pro, 21H1
- WinPython 3.9.4
- Apache24
- Django 3.2.4
- mod_wsgi-4.8.0-cp39-cp39-win_amd64
Actually, there is no change, it got even worse. i.e. this wake up situation occurs more often.
Remember: Changing WinPython 3.9.4 to WinPython 3.7.7 with mod_wsgi-4.7.1-cp37-cp37m-win_amd64 and all works fine!
Perhaps it's useful to have a stack trace? Here we are:
