> While submitting a topology to a 20 node 40 worker strong cluster, the supervisor keeps throwing errors and keeps restarting the workers it is supervising.
> For this reason the topology never starts, instead it keeps dancing by reassigning the bolts and spouts forever.

> The error basically says:
> {code}
