Magento RDS CPU使用率100％，可疑查询正在运行

Question

即使站点流量很低，我的RDS服务器的CPU使用率也接近100％。

该RDS服务器有20〜30个会话。在mysql服务器上检查进程列表后，我可以看到一个复杂的查询正在消耗所有CPU使用率。

但是，我不确定此查询代码是Magento自然mysql查询还是恶意软件查询。

  count(DISTINCT e.entity_id)
FROM `sales_flat_order_item` AS `order_items`
INNER JOIN `sales_flat_order` AS `order` ON `order`.entity_id = order_items.order_id AND `order`.state <> 'canceled'
LEFT JOIN `catalog_product_entity` AS `e` ON (e.type_id NOT IN ('grouped', 'configurable', 'bundle')) AND e.entity_id = order_items.product_id AND e.entity_type_id = 4
LEFT JOIN `catalog_product_flat_1` AS `cpl` ON e.entity_id = cpl.entity_id
INNER JOIN `catalog_category_produc

我不确定这些查询是恶意软件还是magento自然查询。

我的网站基于Magento 1.9.3.8。

RDS实例类型为m5.xlarge，CPU为4，RAM容量为16GB。

服务器支持团队建议我确认是否为恶意软件，除非我必须对其进行调整以节省资源。
