Grails的内存泄漏的批量上传 - HibernatePersistenceContextInt

我使用的石英工作做一些后端处理，从而导致成批量上传到数据库中。下面给出我明确地清理了会议。

class MyService {
    def sessionFactory
    static transactional = false

    def runJob() {
        def collectionOfDomain = []
        for {
            collectionOfDomain.add(someData)
            if(collectionOfDomain.size() == 200) {
                SomeDomain.saveAll(collectionOfDomain)
                sessionFactory.currentSession.flush()
                sessionFactory.currentSession.clear()
                collectionOfDomain.clear()
            }
        }
    }
}

我的过程中运行良好的某些情况下，很少有成功执行后，我看到在日志下面的错误。我看到了同样的错误，当我关闭服务器。我使用的Grails 2.3.6和Postgres和Hibernate 3.6.x的

非常感谢你的帮助！！！
