I believe this is due to a bug in the quota code that doesn't close the quota file after deleting a mailbox. I consistently get this behavior trying to delete a user that has more than ~250 mailboxes. (ulimit -f is 255) If you delete the user's quota first you shouldn't get this error, at least if you're running into the same bug I've seen. Assuming you've patched cyrus to allow quota roots to be removed, "sq user.username remove 0" will delete the quota root. I spent a couple hours trying to track the bug down to no avail.
