Я использую SQLite с Hibernate и получаю следующее исключение.Может быть, я хочу хранить слишком много данных?Есть ли ограничение на размер данных?Кто-нибудь знает проблему?

Java-код.Здесь я пытаюсь сохранить модель в БД и где я получаю исключение. 

Session session = null;
        Transaction tx = null;
        try {
            System.out.println("[INFO] saveModelToDB() Started!");
            session = getSessionFactory().openSession();
            tx = session.beginTransaction();
            // search for existing model in db
            List l = session.createCriteria(Model.class).list();
            // there is a Model ?
            if(!l.isEmpty()) {
                model = (Model) l.get(0);
                // delete old model
                session.delete(model);
                // force an db update to avoid side effects
                tx.commit();
                // start a new transaction for saving the Model
                tx = session.beginTransaction();
                // persist the ne model
                session.merge(model);
            }
            else {
                session.merge(model);
            }
            tx.commit();
            System.out.println("[INFO] saveModelToDB() Finished!");
