How It Affects Your App
This error indicates that the authentication token used by the application does not match the token stored in the MySQL server. This can prevent the application from connecting to the MySQL server, resulting in an inability to access the data stored in the database. This can cause the application to become unresponsive or crash, leading to a disruption of service.
How To Fix
1. Check the error log for the MySQL 3136 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for the max_allowed_packet setting:
$ grep max_allowed_packet /etc/mysql/my.cnf
3. Increase the max_allowed_packet setting to a higher value:
max_allowed_packet = 16M
4. Restart the MySQL server:
$ sudo service mysql restart
5. Check the error log again to make sure the MySQL 3136 error is gone:
$ tail -f /var/log/mysql/error.log
6. Use an automated database observability tool to monitor and fix the MySQL 3136 in question. Automated database observability tools can provide real-time insights into the performance and health of your database, allowing you to quickly identify and fix any issues that arise. They can also provide detailed metrics and logs that can help you diagnose and troubleshoot any issues that may arise.
