最近mysql slave上频发'Relay log read failure'错误

[netxuning]

哪怕是在master上执行了alter table的操作都会导致同步产生如下错误：
Last_SQL_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master's
binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can
check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave.

然后再很麻烦地恢复同步。以前并不这样 。。。

最近做过什么大的变动没 比如新增加一台slave，重启数据库，修改动态参数之类的

建议将之前的binlog备份后，清空
