我有一个主/从MySQL复制在生产级别上工作一天，但每天，复制停止工作。但是每件事都说没关系：
显示奴隶状态; show Slave_IO_Running和Slave_SQL_Running是的。
如果我执行：
stop slave;
SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
start slave;
复制再次起作用并且＃34;秒落后于主人＆＃34;开始下降到零。但我需要找到什么打破复制。
深入挖掘，我在mysql.log找到了这个：
2017-06-17 00:19:48 3084 [注意]＆＃39; SQL_SLAVE_SKIP_COUNTER = 1＆＃39;执行于 relay_log_file =＆＃39; ./ mysqld-relay-bin.000055＆＃39;，relay_log_pos =＆＃39; 632837719＆＃39;， master_log_name =＆＃39; mysql-bin.000046＆＃39;，master_log_pos =＆＃39; 632837556＆＃39;和新的 位于relay_log_file =＆＃39; ./ mysqld-relay-bin.000055＆＃39;， relay_log_pos =＆＃39; 638878870＆＃39;，master_log_name =＆＃39; mysql-bin.000046＆＃39;， MASTER_LOG_POS =＆＃39; 638878707＆＃39;
所以我执行了：
[root@ip-172-31-19-9 mysql]# mysqlbinlog --no-defaults -v mysql-bin.000046 --start-position=632837554 --stop-position=632837558
结果是：

这是"event_type: 68"是什么？任何线索？
