Hi Alain, Im only speculating here, but id wager to say that this isn't the same key always, but rather multiple different keys that you know to exist?
If that's the case it's possible that with notfound_ok: true sometimes Riak will return a not found if a vnode in the preflist responds back without the data, due to a partial write. Can you provide more info and/or logs?
