The reason for this is that the django qcluster component polls the
database regularly:
https://github.com/Koed00/django-q/issues/139
https://django-q.readthedocs.io/en/latest/configure.html#poll
IMO it would make sense to make the qcluster component optional, since
there are cronjobs anyway. But that's an upstream issue...
In the meanwhile debian could configure a lower default poll rate. I
have set 5 seconds instead of the default 0.2 in order to reduce
database traffic.
Oh and the issue is related to hyperkitty, which is part of the
mailman3-full metapackage. Maybe someone could tag this issue
accordingly.
Thanks,
Stefan
