How It Affects Your App
MySQL 1301 ER_WARN_ALLOWED_PACKET_OVERFLOWED indicates that the maximum packet size allowed by the server has been exceeded. This can cause the application to experience performance issues, as the server will be unable to process requests that exceed the maximum packet size.
