Which OS / kernel version are you using ?

You can delete the mailboxes.db and restart cyrus, then you can run
ctl_mboxlist -m on the backends
You could also recover the mailboxes.db getting it from the hot backup
in the db.backup1/2 directories and then run ctl_mboxlist -m on the
backends. That would work only if your hot backup isnt already corrupted

Im not sure. I've done it in the past and didnt notice any problems.
