    Thanks for the review @uce. @StephanEwen actually discovered this problem. The problem
was related to #2700. When the scheduleOrUpdateConsumers call was triggered when in state
restarting due to a late rpc, it would fail the complete `ExecutionGraph`, because it could
not find the respective `Execution`.
    
    Will rebase the PR, because release-1.1 contained a problem which prevented it from building.

> When in state {{RESTARTING}} it is possible to fail the {{ExecutionGraph}}. This should
not be possible, since in state {{RESTARTING}} there should be no action performed which can
fail the {{ExecutionGraph}}.
