OK, so not very big.

You can delete them, but somehow I doubt that helps.. That error message anyway happens when a session has opened the mbox and is "syncing" it. This normally is a pretty fast operation, but the error message indicates that another session saw the first session doing it for over 3 minutes until it aborted.
Do you have hanging imap processes eating 100% CPU? That could explain it if Dovecot doesn't like something in the mbox file. Also there may have been some other reasons for this that are already fixed in newer versions.
