Lmtp having problems opening deliver.db

[Russell Gnann]

We are running the following Cyrus-IMAP 2.1.12/Cyrus-SASL 2.1.13

We have been having a recurring error show up in our message logs..

Jul 15 09:45:23 tom lmtpd[13549]: DBERROR: opening /var/imap/deliver.db: Not
enough space
Jul 15 09:45:23 tom lmtpd[13549]: DBERROR: opening /var/imap/deliver.db:
cyrusdb error
Jul 15 09:45:23 tom lmtpd[13549]: lmtpd: unable to init duplicate delivery
database

I am not too familiar with the purpose of the deliver.db other than it's use
in duplicate message suppression.  My initial solution was to delete the
deliver.db file since it seemed to be corrupt and restart cyrus IMAP. This
seemed to fix the problem as lmtp seemed to have no trouble creating and
updating a new version.  Now a few days later we are seeing these errors.
We are use Berkey DB 4.1.25 for this file. It doesn't seem to be hampering
our mail usage, but I would like to learn how to deal with this
appropriately. Any help would be greatly appreciated.  Thanks.

Our current IMAP configs are..
