MySQL 1776

This error indicates that the slave is unable to read the master's binary log position, which is necessary for replication.

How It Affects Your App

MySQL 1776 ER_BAD_SLAVE_AUTO_POSITION is an error that occurs when a slave server is unable to read the master server's binary log. This can cause replication to fail, resulting in data loss or inconsistency between the master and slave servers. This can have a significant impact on an application, as it can lead to data corruption, data loss, or application downtime. Additionally, it can cause the application to become unresponsive or slow, as the replication process is interrupted.

How To Fix

1. Check the MySQL error log for more information about the error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:
$ cat /etc/mysql/my.cnf
3. Check the MySQL process list to see if any queries are running for an extended period of time:
$ mysqladmin -u root -p processlist
4. Check the MySQL system variables to see if any of them are set to an incorrect value:
$ mysql -u root -p -e "SHOW VARIABLES"
5. Check the MySQL user privileges to see if any of them are set to an incorrect value:
$ mysql -u root -p -e "SHOW GRANTS"
6. Check the MySQL database tables for any corruptions:
$ mysqlcheck -u root -p --all-databases
7. Check the MySQL server status to see if any of the values are out of range:
$ mysqladmin -u root -p status
