Hello,

I tried to upgrade from 2.0.15 to 2.1.rc1 over the weekend but ran into some problems with squat. My two largest mailboxes were corrupted, producing this error:

Nov 27 17:38:12 kerio1 dovecot[42860]: imap(bigmailbox): Error: Corrupted squat uidlist file /var/mail/metro-email.com/bigmailbox/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.search.uids: wrong indexid

There is a good chance that I had shot my own foot, by forgetting to update postfix's dovecot-lda reference to the new instance. I had also enabled an inet based LMTP listener, although it is not being used yet.

Even using non-corrupted indexes, it seemed that FTS was not being used. A basic search such as this one took many minutes to complete:

doveadm search -u jsample mailbox INBOX body eps

I found messages like this in mail.log after performing the search:

Nov 27 18:21:39 kerio1 dovecot[42860]: indexer-worker(jsample): Indexed 0 messages in Drafts Nov 27 18:21:39 kerio1 dovecot[42860]: indexer-worker(jsample): Indexed 0 messages in INBOX

When I rolled back to 2.0.15, the same search returned almost immediately. The larger mailboxes went quickly again, but only after they had a chance to rebuild.

A few other notes about our configuration: We are on PPC, with the stats service disabled (because of kqueue issue discussed earlier). I made some minor changes in my config since the previous installed version (diff below). mail_location override is in place for all users via password file, e.g.: userdb_mail=mdbox:/var/mail/metro-email.com/jsample/mdbox

Thanks, Tony
