This error message is typically encountered in database systems such as MySQL, and it indicates that a transaction has been blocked by another transaction for too long. When this happens, the database engine will automatically terminate the blocked transaction to prevent it from causing further delays.
The most common cause of this error is a deadlock, which occurs when two or more transactions are waiting for each other to release resources (such as locks) that they need to complete their operations. In some cases, the problem can be resolved by simply restarting the transaction or by increasing the length of the timeout period. However, in more serious cases, it may be necessary to analyze the database schema and application code to identify and resolve the underlying issue.
To address this error, you can try the following steps:
1. Restart the transaction by rolling back the current one and starting a new one.
2. Increase the timeout period to allow the transaction more time to complete.
3. Analyze the database schema and application code to identify and resolve the underlying issue causing the deadlock.
4. Optimize the queries being used in the transaction to reduce the amount of time required to acquire and release locks on resources.
