Comment (by guettli):
I created this ticket two years ago. I think a guideline is enough here.
I resolved my issues by checking that no ORM code gets executed before the
multiprocessing module spawns the workers.
In other words:
1. start the workers via multiprocessing.
2. connect to DB.
If you have N workers, you need N connections to the database.
I think no change to the django code base is necessary. Just docs.
