RRV Bucket is corrupt

Does anyone know what causes this error and if there is a way other than restoring from backup to repair? I’ve seen suggestions that adding a certain entry (DEBUG_FIXUP_DELETE_ERRORS_INCLUDE=2B8,227,) to the notes.ini file and then running a reboot will allow us to run fixup on the corrupt db.

Basically it is likely to be unrecovereable
