Планировщик остановлен, когда в Spring Transaction произошел тупик

Я разработал приложение для мониторинга, которое использует Spring-3.0 Hibernate-3.6.5 с SpringHibernateTemplate в качестве DAO. База данных SQL Server 2008. Это приложение имеет длительные транзакции каждый день.

@Repository("areaDaoHibernate")
public class AreaDAO implements IArea {
       protected HibernateTemplate template = null;

       @Autowired @Required
       public void setSessionFactory(SessionFactory sessionFactory) {
              template = new HibernateTemplate(sessionFactory);
       }

       // basic dao method
}

Это приложение имеет некоторое планирование (реализует Runable) через springbeans.

@Component("dailyTask")
@Scope("prototype")
public class DailyTask implements Runnable {

@Override
       public void run() {
              // running task
       }
}

Это приложение использует Apache DBCP для объединения.

   <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
              <property name="dataSource">
                     <ref bean="CustodyDataSource" />
              </property>
…
       </bean>

<bean id = "CustodyDataSource"
      class             = "org.apache.commons.dbcp.BasicDataSource"
      p:driverClassName = "${jdbc1.driverClassName}"
      p:url             = "${jdbc1.url}"
      p:username        = "${jdbc1.username}"
      p:password        = "${jdbc1.password}"
      p:maxIdle         = "${jdbc1.maxIdle}"
      p:maxActive       = "${jdbc1.maxActive}" 
      p:validationQuery = "${jdbc1.validationQuery}" 
      p:testWhileIdle   = "${jdbc1.testWhileIdle}" />
<bean id = "transactionManager"
      class = "org.springframework.orm.hibernate3.HibernateTransactionManager"
      p:sessionFactory-ref = "sessionFactory" />

У меня проблема, когда это приложение блокируется, планирование прекращает работу.
Появляется ошибка:

Итак, мои вопросы:

1. Должен ли я изменить пул соединений, чтобы избежать проблемы взаимоблокировки?
2. Почему мой компонент планирования останавливается после возникновения тупика?
