寻求帮助：JDBC连接400并监听DATAQUEUE

leanrabbit

最近公司做了一个数据接口，在linux上开发Java程序实时监听并接收AS400上的DataQueue的消息，关键代码如下：

      /** sysConn 定义系统连接，dqPath 定义DataQueue路径 */
      DataQueue dq = new DataQueue(sysConn, dqPath);

      String request = null;
      
      while (true){
         request = dq.read(-1).getString();
        /**
         * 对request进行处理
      * 不再对dq进行操作
      *
         */

        }

现在出现的问题是，在接收一次数据之后，程序继续循环使用dq.read(-1)监听，大概空闲一个小时多一点时间后，AS400上JOBLOG中出现连接错误信息，dq.read(-1)不报错但是监听不到DataQueue的数据。
AS400上JOBLOG日志如下，各位大侠给看看是什么原因，非常感谢！
