A task that runs longer than the broker's visibility timeout is redelivered while its first run is still going. The idempotency lease correctly stops the duplicate from doing the work, but the duplicate then re-queued itself once per LEASE_TTL until celery ran out of retries and raised MaxRetriesExceededError — so a perfectly healthy long task (a large graph extraction is the one that found this) reported a task failure, with a traceback, while the real run was still making progress next to it. Catch the exhaustion and return a "deferred" result instead. A normal deferral still re-queues: only the give-up path changes, and the lease holder's dedup row is left untouched so its own completion still records.
