Occasional (or even semi-frequent) failure to get lock is a normal thing. All it means is that another SA process was already updating the database, due to some other message being autolearned, or the expiry process running. Rather than hold up the mail queue waiting for the previous process to finish, SA fails to learn the message and moves on. Unless you always get autolearn=failed, don't worry about it.
