MariaDB Error 1461: Too Many Prepared Statements
Description
This error indicates that your MariaDB session has reached the maximum allowed number of prepared statements, as defined by the `max_prepared_stmt_count` server variable. It typically occurs when an application creates prepared statements without properly deallocating them, or when a single session attempts to prepare an unusually large number of unique statements.
Error Message
Can't create more than max_prepared_stmt_count statements (current value: %lu)
Known Causes
3 known causesApplication Statement Leakage
The application creates prepared statements but fails to explicitly close or deallocate them after use, leading to a gradual accumulation within the session.
Excessive Statement Preparation
The application logic frequently prepares new, unique SQL statements instead of reusing existing ones, rapidly consuming the session's allocated limit.
Insufficient Server Configuration
The `max_prepared_stmt_count` server variable is set too low for the application's actual needs, even if statements are generally managed correctly.
