While inspecting the logs of the worker I stumbled upon:

future: <_GatheringFuture finished exception=CancelledError()>
concurrent.futures._base.CancelledError

@jmorel Did you manage to reproduce it =) ?

No, never. And since it happened on a server which had its disks full, it may just be a side effect.
