[Bug 452767] [NEW] infinite loop printing errors if deliver.db is corrupt

[Kent Tong]

Public bug reported:

Binary package hint: kolab-cyrus-imapd

kolab-cyrus-imapd   2.2.13-3ubuntu2 on Ubuntu hardy 8.04.3 LTS.

If the /var/lib/cyrus/deliver.db is corrupt, cyr_expire will keep
printing out the same error forever, quickly exhausting the hard disk.

The workaround is to stop cyrus and delete the db file.

However, this is a very serious as it causes a DoS on the whole server.
