In parallel.controller.hub, the registration_timeout is set to max(5000, 2*self.heartmonitor.period) and must be an integer, but self.heartmonitor.period is a float.

So, when the period is more than 2500 (doesn't happen with the default value of 1000; only with user-modified values that are higher), a validation error occurs and the hub doesn't start.
