centos7 django+nginx 环境下的网站经常性的出现：无法访问此网站 xxxxx.com 的响应时间太长。。。如图

是 mysql 吗，可以试试搜索关键字 django mysql 2006 gone away ，这个可能性比较高

@Vegetable 是的.mysql ，谢谢。我搜一下看看

Django 用啥跑的，我用着没有问题啊

@zachlhb centos+ nginx +uwsgi 以前也没有遇到这样的事。最近换了台 tx 的云服务器。就这样了。也查不到原因。

你这看起来是
浏览器-nginx 之间，建立 tcp 连接 超时
和 django 大概没什么关系

同意楼上，看现象连 nginx 的报错页面都没刷出来，说明是连接 nginx 的问题

@julyclyde
@lybcyd
如果是这种情况，怎么排查处理？如果只是我这台电脑有问题？那就不用管了。就怕是全部访问用户都会遇到。不知道是不是服务器上的问题。

曾经遇到过同样的问题，最后鸡贼的鹅厂说要使用按流量付费，结果就好了。

@jmspark 是他们云服务器带宽的问题？ 你现在一直用按流量付费？ 奇怪的是我别的云服务器没这问题。一样的配置环境。

@python30 是的，按流量付费。当时带宽上到 50 都不行，直接上到 100 就正常了。

@jmspark 莫非是流量大的时候才会出现这情况

@python30 是的
