Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction

Modify the method "_execute" in file "lib\Zend\Db\Statement\Pdo.php".

Original code:

/**
 * Executes a prepared statement.
 *
 * @param array $params OPTIONAL Values to bind to parameter placeholders.
 * @return bool
 * @throws Zend_Db_Statement_Exception
 */
public function _execute(array $params = null)
{
    try {
        if ($params !== null) {
            return $this->_stmt->execute($params);
        } else {
            return $this->_stmt->execute();
        }
    } catch (PDOException $e) {
        #require_once 'Zend/Db/Statement/Exception.php';
        throw new Zend_Db_Statement_Exception($e->getMessage(), (int) $e->getCode(), $e);
    }
}

New code:

public function _execute(array $params = null)
{
    $max_tries = 3;
    $tries = 0;
    do {
        $retry = false;
        try {
            if ($params !== null) {
                return $this->_stmt->execute($params);
            } else {
                return $this->_stmt->execute();
            }
        } catch (PDOException $e) {
            if ($tries < $max_tries && $e->getMessage()=='SQLSTATE[40001]: Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction') {
                $retry = true;
                sleep(1);
            } else {
                throw new Zend_Db_Statement_Exception($e->getMessage(), (int) $e->getCode(), $e);
            }
            $tries++;
        }
    } while ($retry);
}
