Good day, All.

My issue looks very similar to [https://www.percona.com/blog/2013/09/16/possible-reasons-when-mysql-replication-lag-is-flapping-between-0-and-xxxxx/](https://www.percona.com/blog/2013/09/16/possible-reasons-when-mysql-replication-lag-is-flapping-between-0-and-xxxxx/)

As i can not ask in that thread anymore, here is the new thread.

Looks to me that my issue to be the same as 🙂

#### 2. Dual-master setup, “log\_slave\_updates” enabled, server-ids changed.

Tried:  
STOP SLAVE; CHNAGE MASTER TO MASTER\_LOG\_POS=${a\_new\_number\_from\_show\_master\_status\_command\_on\_the\_master}; START SLAVE;

However, the issue is still there.

Please shed some light.

Thanks a lot in advance
