**显示为脏数据的这条数据重新导入时又成功了，数据完全没有变过，但是这个表经常报这种错，请问这种问题怎么解决，如何排查出错原因**

Start with the reported SQL Server logs and the reader entry points in CommonRdbmsReader.java, SqlServerReader.java, and ReaderRunner.java. Reproduce the intermittent “The connection is closed” failure and trace how the connection error becomes dirty data and stops the task. Done means the failure cause is identified and the issue defines a tested handling or recovery change.
