MySQL replication lag is flapping between 0 and XXXXX

MySQL & MariaDB
1

Good day, All.

My issue looks very similar to 5 reasons why 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 :slight_smile:

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
