> Affects Versions: 1.5.1, 1.6.0

>
> Currently, it is possible to fail slot allocations in the {{SlotPool}}.
> Failing an allocation means that the slot is removed from the {{SlotPool}}.
> If we have removed all slots from a {{TaskExecutor}}, then we should also
> release/close the connection to this {{TaskExecutor}}. At the moment, this
> only happens via the heartbeats if the {{TaskExecutor}} has become
> unreachable.
