How It Affects Your App

This error indicates that the checksum of a binary log event is invalid. This can cause replication to fail, resulting in data inconsistency between the master and slave databases. This can lead to data loss or corruption, and can cause applications to malfunction or crash. It is important to identify and fix the root cause of this error to ensure the integrity of the data and the proper functioning of the application.

3. Check the MySQL process list to see if any processes are running that could be causing the error:
$ mysqladmin -u root -p processlist
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:
$ service mysql restart
