The POSKey error for object 0 can be ignored. It is normal. When the
database is opened for the first time, it tries to load object 0 and
then creates it if it doesn't exist. I don't see any other errors in
your log output from the server.
In your client code, try adding:
import logging
logging.getLogger().setLevel(logging.INFO)
logging.getLogger().addHandler(logging.StreamHandler())
and see if this gives more useful logging info on the client.
