Package: uwsgi-plugin-python3
Version: 2.0.15-11+b2
Severity: normal
I'm using uwsgi to drive radicale using the python3 plugin.
My configuration is minimal, with a single master instance only running
radicale:
/usr/bin/uwsgi --master --ini /etc/uwsgi/radicale.ini
the ini contains:
[uwsgi]
threads = 2
manage-script-name = true
plugin = python3
mount = /url=/usr/share/radicale/radicale.wsgi
logto = /var/log/radicale/uwsgi.log
In my .service file I'm using:
[Service]
KillSignal=SIGQUIT
Everything works. However, on SIGSTOP, uwsgi reliably crashes:

I also tried to use --die-on-term instead of sending SIGQUIT, but the
behavior is the same.
