His isn't, but I have users with 500MB to a GB mailbox. Could they be the cause of the problem?

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?

Also there may have been some other reasons for this that are already fixed in newer versions. I looked at the upgrade list on the server and dovecot isn't showing any upgrades via atp-get
