MySQL 1181

This error occurs when an error is encountered during a rollback operation in MySQL 1181. It indicates that the rollback was unsuccessful and the transaction was not completed.

How It Affects Your App

The impact of MySQL 1181 ER_ERROR_DURING_ROLLBACK on an application is that it prevents the application from completing a transaction. This can lead to data inconsistency and data loss, as the transaction is not completed and the changes are not applied. It can also lead to application downtime, as the application may be unable to continue functioning until the issue is resolved. This can have a significant impact on the user experience and the overall performance of the application.

How To Fix

1. Check the error log for the MySQL 1181 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:
$ cat /etc/mysql/my.cnf
3. Check the MySQL process list for any suspicious activity:
$ mysqladmin -u root -p processlist
4. Check the MySQL user table for any suspicious users:
$ mysql -u root -p -e "SELECT User, Host FROM mysql.user;"
5. Check the MySQL grants table for any suspicious grants:
$ mysql -u root -p -e "SELECT User, Host, Grant_priv FROM mysql.user;"
6. Check the MySQL privileges table for any suspicious privileges:
$ mysql -u root -p -e "SELECT User, Host, Privilege FROM mysql.user;"
7. Check the MySQL tables for any suspicious data:
$ mysql -u root -p -e "SELECT * FROM mysql.table;"
8. Check the MySQL logs for any suspicious activity:
$ mysql -u root -p -e "SELECT * FROM mysql.log;"
9. Check the MySQL system variables for any misconfigurations:
$ mysql -u root -p -e "SHOW VARIABLES;"
10. Check the MySQL status variables for any misconfigurations:
