服务运行一段时间后，服务接口异常，无法返回数据

一、该问题的重现步骤是什么？

1.  blade-data-transfer服务运行一段时间后（几天），GET: /blade-data-transfer/datatransferlog/page 接口异常，无法返回数据，Nacos显示正常

Failed to handle request [GET http://11.11.152.52/blade-data-transfer/datatransferlog/page?current=1&size=10]: finishConnect(..) failed: Connection refused: /11.11.152.52:8389

二、你期待的结果是什么？实际看到的又是什么？

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

2.7.1 

CentOS 7

四、请提供详细的错误堆栈信息，这很重要。
