停靠的nginx“；超时“；几分钟后

我使用库存nginx图像在docker容器中运行nginx。它正在代理运行django应用程序的gunicorn

最后一次连接5秒后，我看到一个“client 172.18.64.88 closed keepalive connection”的数字。然后，如果我等待5分钟或更长时间，第一次尝试的连接将在客户端出错。如果我立即点击Firefox默认设置的“重试”按钮来解决连接问题，它就会连接

我目前正在使用docker 1.90rc1和nginx 1.9.5

nginx -V
nginx version: nginx/1.9.5

我也经历过很多docker挂起。Docker会经常挂断几分钟或更长时间，直到我必须重新启动箱子。目前还不完全确定如何调试它

以下是nginx容器的检查步骤：
