Yii2 is mercilessly leaky. what to do?

Question

Yii

there is such a simple thing

Console::startProgress($done, $total);
 foreach ($udi as $key => $item) {
            $changedItem = \Yii::$app->db->createCommand('select overprice, overprice_type from shop_product_changed_dealer where dealer_item_id=:id',[':id' => $item['id']])->queryOne();
            $done++;
            if ($done % 1000 == 0) {
                gc_collect_cycles();
                print_r(memory_get_usage() . "\n");
                Console::updateProgress($done, $total);
            }
        }

Yii::$app->db is leaking relentlessly. leaves no chance.
