How It Affects Your App
MySQL 3132 ER_LOCKING_SERVICE_DEADLOCK can cause an application to become unresponsive or crash. This is because the error occurs when two or more transactions are waiting for each other to finish before they can proceed. As a result, the application can become stuck in a loop, unable to complete any of the transactions. This can lead to data corruption, lost data, and other issues. It is important to identify and address this error quickly to prevent further damage to the application.
