尝试处理下一行失败。结束的结果集错误

Question

执行批处理作业时出现以下错误。不是立即但是半小时后。

2016-02-17 15:24:25,106 ERROR [AbstractStep        ][poolTaskExecutor-2  ] Encountered an error executing step processSubscriptionFile-stepTwo in job subscriptionJob
org.springframework.jdbc.UncategorizedSQLException: Attempt to process next row failed; uncategorized SQLException for SQL [

                    SELECT DISTINCT PERSON_ID FROM CUST_SUB_INTER where job_id = 77317301 order by PERSON_ID

            ]; SQL state [99999]; error code [17010]; Closed Resultset: next; nested exception is java.sql.SQLException: Closed Resultset: next
    at org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator.translate(AbstractFallbackSQLExceptionTranslator.java:84)
    at 

我的批处理作业文件如下。在第一步中，我正在从文件中读取数据并添加到中间表中。此块使用分区和多个线程。此步骤使用分区和线程。在第二步中，我将此临时表中的数据作为不同的客户ID读取并将其传递给writer。它失败了一半。中间表中有70000条记录，10000个不同的客户ID。第二步不使用分区和线程。请帮忙
