Hi Stéphane,
I've hit the same problem while migrating my Django sites from Debian Buster to
Bullseye.
In my case, setting "WSGIApplicationGroup" to "%{GLOBAL}" doesn't help much.
But I found another solution, by enabling Daemon mode, as recommended by the
Django docs:
https://docs.djangoproject.com/en/3.2/howto/deployment/wsgi/modwsgi/#using-mod-wsgi-daemon-mode
So I added these two lines in each site (with appropriate domain name) and it
works fine:
WSGIDaemonProcess example.com
WSGIProcessGroup example.com
Hope it helps.
