How It Affects Your App
MySQL 1205 ER_LOCK_WAIT_TIMEOUT indicates that a transaction has been waiting too long for a lock. This can cause the application to become unresponsive or even crash. It can also lead to data inconsistency and data loss. The application may also experience performance issues due to the lock wait timeout. To prevent this error, the application should be designed to handle lock wait timeouts gracefully.
How To Fix
1. Check the error log for the MySQL 1205 error. This can be done by running the following command:
mysql> SHOW GLOBAL ERROR LOG;
2. Check the status of the table locks. This can be done by running the following command:
mysql> SHOW OPEN TABLES WHERE In_use > 0;
3. Kill the process that is causing the lock. This can be done by running the following command:
mysql> KILL ;
4. Flush the table locks. This can be done by running the following command:
mysql> FLUSH TABLES;
5. Use an automated database observability tool to monitor and fix the MySQL 1205 in question. Automated database observability tools can help identify and diagnose issues quickly, as well as provide insights into the performance of the database. They can also provide alerts when issues arise, allowing for quick resolution.
