批量上传的Grails内存泄漏 - HibernatePersistenceContextInterceptor

Question

我正在使用Quartz作业进行一些后端处理，这会导致批量上传到数据库。我明确地清理了下面给出的会议。

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()
            }
        }
    }
}

我的进程在某些情况下运行良好，并且在几次成功执行后，我在日志中看到以下错误。我关闭服务器时看到同样的错误。我正在使用Grails 2.3.6和Postgres和Hibernate 3.6.x

非常感谢你的帮助!!!
