错误信息：

Last_Error:
 ... The slave coordinator and worker threads are stopped, possibly leaving data in inconsistent state. A restart should restore consistency automatically, although using non-transactional storage for data or info tables or DDL queries could lead to problems. In such cases you have to examine your data (see documentation for details).

解决方法：
关闭并行复制

STOP SLAVE;
SET GLOBAL slave_parallel_workers=0;
