> In case that the TaskManager fatally fails and some of the failing node's slots are SharedSlots, then the slots are not properly released by the JobManager. This causes that the corresponding job will not be properly failed, leaving the system in a corrupted state.
> The reason for that is that the AllocatedSlot is not aware of being treated as a SharedSlot and thus he cannot release the associated SubSlots.
