1205 - Lock wait timeout exceeded; try restarting transaction

This error message indicates that a particular transaction has exceeded the maximum time allowed for waiting to acquire a lock on a table or a row in a table. The lock is used to ensure that concurrent transactions do not interfere with each other while accessing or modifying the same data.

To resolve this error, you may try restarting the transaction. This can be done by rolling back the current transaction and starting a new one. Alternatively, you may need to adjust the timeout settings for the lock or optimize the database schema and queries to reduce the likelihood of lock contention.

It is also important to identify the root cause of the lock contention, which may include factors such as a high volume of concurrent transactions, inefficient queries or indexing, or inadequate hardware resources. Addressing these underlying issues can help prevent similar errors from occurring in the future.
