How It Affects Your App
This error indicates that the application is unable to find the authentication token associated with the MySQL server. This can prevent the application from connecting to the 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. Additionally, the application may be unable to perform any operations that require access to the database, such as creating, updating, or deleting records.
How To Fix
1. Check the error log for the MySQL 3137 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 service:
$ sudo service mysql restart
5. Check the error log again to confirm the MySQL 3137 error is resolved:
$ tail -f /var/log/mysql/error.log
6. Use an automated database observability tool to monitor and fix the MySQL 3137 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 address any issues that arise. This can help you proactively prevent MySQL 3137 errors from occurring in the future.
