That's what I was afraid of.

FileStorage indexes can't be saved after they reach a certain size,  
where size roughly based on the number of objects.

I need to find a way to fix this.

 >>> import ZEO.ClientStorage
 >>> len(ZEO.ClientStorage.ClientStorage(addr)

where addr if the address of your storage server as a host, port tuple.
