How It Affects Your App
MySQL 1569 ER_DUP_ENTRY_AUTOINCREMENT_CASE error occurs when an application attempts to insert a duplicate value into a column that has been set to auto-increment. This can cause the application to fail, as the database will not be able to insert the duplicate value. This can lead to data integrity issues, as the application may not be able to store the data it needs to. Additionally, it can lead to data loss, as the application may not be able to store the data it needs to.

max_allowed_packet = 16M
4. Restart the MySQL server:
$ sudo service mysql restart
