Php Magento网站不工作（超时）管理员页面正在工作

问题是： 当我尝试访问任何页面（如主页/产品页面）时，网站突然无法加载我收到cloudflare“错误524发生超时”。什么工程是直接链接到标志或管理面板工程伟大。只有主网站未加载

我的服务器： Centos 6.5 nginx+php-fpm+percona

错误日志： Magento文件夹/var/report/

Magento文件夹/var/log/system.log这两个错误我可以识别为2个扩展的一部分不确定这是否会导致这样的问题，但我已经包含了它

我在mysqld.log中没有看到任何错误

所有这些错误对我来说都很小，这些错误会导致我的问题吗？如果不是，如何找到真正导致我问题的原因？我注意到网站工作了几次，有时总是超时，但速度很慢

更多信息：商店有65k产品，我也有针对速度/流量等优化的大多数配置文件。这是搜索栏，它有子类别，它试图加载很多类别，并且超时，删除了按类别搜索，效果很好！没有服务器问题
