changed, the following crash could happen again during replication:

  File "neo/scripts/neostorage.py", line 66, in main
    app.run()
  File "neo/storage/app.py", line 147, in run
    self._run()
  File "neo/storage/app.py", line 178, in _run
    self.doOperation()
  File "neo/storage/app.py", line 258, in doOperation
    _poll(0)
