I guess you mean you ran it while users could still be making changes?

Those should go away automatically. Don't worry about them.

Message's flags were changed between two rsyncs, so the same message got
transferred twice but with different filenames. Dovecot now created a
duplicate message (since it thought that it's safer to create a
duplicate than to delete a non-duplicate).

All of the index errors will go away too.

The next time you could do it with dsync to avoid these kind of
problems.
