How It Affects Your App
MySQL 1624 ER_SLAVE_HEARTBEAT_VALUE_OUT_OF_RANGE indicates that the heartbeat value set for the slave is not within the acceptable range. This can cause replication issues, as the master and slave will not be able to communicate properly. This can lead to data loss or corruption, as the slave will not be able to keep up with the master. In addition, the application may experience performance issues due to the replication lag. Therefore, it is important to ensure that the heartbeat value is set correctly to avoid these issues.
How To Fix
1. Check the error log for the MySQL 1624 error:
$ tail -f /var/log/mysql/error.log
