Dear Emmanuel,
I see what you are describing as the trouble point. The server would have to stay running for the entire timeout or until the last client requests its next WU.
Alternately, could a separate much smaller process be provided, which could be run on the server machine to take care of the graceful exit for the tardy clients? That would provide users an option.
Another alternative in my case, would be to provide a manner to tell the clients to shut down if there hasn't been a new WU for <time>.
Is there a section in the code I could study to see if I can provide something for my own use?
Sincerely,
Edwin Hall

Yes, this is a good suggestion.
Implementation is trickier than it seems. We're touching on some of the
brittle aspects of the cado-nfs server, here. The server would have to
wait for the clients to ask for work so that it gets a chance to answer
410. Presumably, waiting for (what the server think is) the clients sleep
time could be appropriate.
I may have a try at this, but that won't be immediate.
Best regards,
E.
