BDB does not work across multiple machines, its transaction support relies on a shared memory region to handle locking so any shared memory architecture (with multiple CPUs) works fine but separate machines and a NAS device don't work. You'll have to use the Postgres store (5x slower, but reasonably scalable) if you want concurrent access to a single Elephant DB from multiple machines.
