How It Affects Your App
MySQL 3086 ER_SLAVE_CHANNEL_SQL_SKIP_COUNTER indicates that the replication slave has encountered an error while attempting to replicate a statement from the master. This can cause the application to become out of sync with the master, resulting in data inconsistencies and potential data loss. It can also lead to replication lag, which can cause the application to become unresponsive or slow. In addition, it can cause replication errors, which can lead to further data loss or corruption.
How To Fix
1. Check the error log for the MySQL 3086 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for the correct port number:
$ cat /etc/mysql/my.cnf
3. Update the port number in the configuration file to the correct port number:
$ sudo nano /etc/mysql/my.cnf
4. Restart the MySQL service:
$ sudo service mysql restart
5. Check the error log again to make sure the MySQL 3086 error is gone:
$ tail -f /var/log/mysql/error.log
6. Use an automated database observability tool to monitor and fix the MySQL 3086 in question. Automated database observability tools can help identify and diagnose MySQL errors quickly and accurately, as well as provide real-time monitoring and alerting of any issues that may arise. This can help ensure that any MySQL errors are addressed quickly and efficiently, and can help prevent future issues from occurring.
