How It Affects Your App
MySQL 1027 ER_FILE_USED error indicates that a file is already in use by another process. This can have a significant impact on an application as it can prevent the application from accessing the file, resulting in errors or unexpected behavior. It can also lead to data corruption or data loss if the application is unable to access the file. Additionally, it can cause the application to become unresponsive or crash if the application is unable to access the file.
How To Fix
1. Check the error log for the MySQL 1027 error. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'log_error';
2. Check the user privileges for the user that is trying to connect. This can be done by running the following command:

3. Check the MySQL configuration file for any incorrect settings. This can be done by running the following command:
mysql> SHOW VARIABLES LIKE '%config_file%';
4. Check the MySQL server status. This can be done by running the following command:

5. Check the MySQL server logs for any errors. This can be done by running the following command:
