I'm not sure why you think I am > not using skiplist. This file seems to say I am. What I meant was running skiplist only, then you don't have to worry about BerkeleyDB anymore. The lines below (and also the case that you are using am old version) indicate that you are running Debian? So there may be Debian specific instruction which may not be found on the Cyrus site. > > ella:~# cat /usr/lib/cyrus/cyrus-db-types.active > ANNOTATION skiplist > DBENGINE BerkeleyDB4.2 > DUPLICATE skiplist > MBOX skiplist > PTS berkeley > QUOTA quotalegacy > SEEN skiplist > SUBS flat > TLS berkeley-nosync > > Also, the directions for upgrading a database, found here: > > http://www.cyrusimap.org/docs/cyrus-imapd/2.2.13p1/install-upgrade.php > > under: > > Upgrading from 2.1.x or earlier > General information (ALL SITES) > > give instructions for using the cvt_cyrusdb program to convert the > databases to skiplist: > > /usr/cyrus/bin/cvt_cyrusdb /var/imap/mailboxes.db berkeley > /var/imap/mailboxes.db.new skiplist > mv /var/imap/mailboxes.db.new /var/imap/mailboxes.db > > and the files appear to look exactly the same when you are done as when > you start.

I'm just not sure about the other stuff like __db.001 or Those are the files in $CONFIG/db/ right? They are used by the different DB engines internally. You should be able to remove those file or just ignonre them if the DB's are in a sane state. Simon > the sub files in the same directory as the seen file.
