mysql 创建用户导致 binlog 异常 replcation 中断报错

sunny_zhao0127

mysql 运行正常的情况下 在master 库上新增用户权限 ，发现slave 都挂了
创建用户及赋权命令如下：
mysql> create user test@'%';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> update user set password=password('zsh') where user='test';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0
mysql>  GRANT ALL PRIVILEGES ON *.* TO test@'%' IDENTIFIED BY PASSWORD '*84CC991F2B08632D6B01FC13FDBBA3FED084008F';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

check binlog 发现如下错误：

请教大家 create user 怎么会导致binlog 异常 （replication 也断掉了）……

哪位遇到过这样的情况?多提高贵意见和建议啊
