Well, that's strange then. But since you're using maildir, you should be
able to easily check how many mails he has in the mailbox that can't be
opened? ie. ls Maildir/.folder.name/cur/|wc -l

Did you try if raising mail_process_size helps?

This shouldn't happen, but it looks like there's some bug which causes
it to be added twice there. Anyway, this error is harmless and
completely transparent to client.
