How It Affects Your App
This error indicates that the size of the statement cache is larger than the maximum allowed size. This can cause the application to be unable to execute certain queries, resulting in unexpected behavior and errors. Additionally, the application may experience decreased performance due to the increased size of the statement cache. This can lead to longer query execution times and slower response times for the application.
How To Fix

4. Check the MySQL user privileges to see if any users have been granted too many privileges:
$ mysql -u root -p -e "SELECT User, Host, Password FROM mysql.user;"
5. Check the MySQL database tables for any corruptions:
$ mysqlcheck -u root -p --all-databases
6. Restart the MySQL service to apply any changes made:
$ service mysql restart
