MySQL 3133

This error occurs when the locking service has timed out while waiting for a lock to be released. It is a MySQL server error code 3133.

How It Affects Your App

MySQL 3133 ER_LOCKING_SERVICE_TIMEOUT indicates that the application has exceeded the time limit for acquiring a lock on a table. This can lead to a decrease in performance and an increase in deadlocks, as the application will be unable to access the table until the lock is released. Additionally, the application may be unable to complete certain operations, as the lock is necessary for the completion of the operation. This can lead to a decrease in user experience and a decrease in overall application reliability.

How To Fix

1. Check the error log for the MySQL 3133 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 3133 error is gone:
$ tail -f /var/log/mysql/error.log
6. Use an automated database observability tool to monitor and fix the MySQL 3133 in question.
