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.
