Found the problem,

The size of the container is only "32260" where I would expect it to be 
65536. Seems like the keys that I have defined above, are not allowed to 
be added to the container. Is there any way to over-ride this behavior?
As the keys should only provide a "view" of the containers contents... 
Like selecting from a database.
