Actually - I am not sure if we ever implemented consistent hashing over 
the cluster; if I remember it correctly, the bloom filters need to use 
the same seed for the hash-functions in all cluster nodes to be 

That might be the reason for this to fail (and the error message also 
seems to indicate this).
