A rescue job: diagnose, contain, rebuild, verify in staging before cutover.
The site was failing under a locale-routing bug that wrote an error on every request. The log had reached 9.8 GB and was taking the server with it.

A stable job board with the fault fixed at source rather than papered over with log rotation.
