During bootstrap a controller node checks in app.py that the number of connected slaves is actually equal to desired number of slaves. This check, however, fails if the controller times out waiting for all slaves to come online. Instead, the controller - correctly - warns that the number of online slaves is not equal to the desired number of slaves, yet still proceeds:
