dockerized nginx“超时”几分钟后

我有nginx运行在docker容器使用股票nginx图像。 它是代理运行django应用程序的gunicorn。

最后一次连接5秒后，我看到一些“客户端172.18.64.88closureskeepalive连接”。 然后，如果我等待5分钟或更长时间，则客户端上首次尝试连接错误。 如果我立即点击Firefox默认的连接问题的“再试一次”button，它会连接。

我目前使用docker 1.90rc1和nginx 1.9.5

nginx -V nginx version: nginx/1.9.5 built by gcc 4.9.2 (Debian 4.9.2-10) built with OpenSSL 1.0.1k 8 Jan 2015 TLS SNI support enabled configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-threads --with-stream --with-stream_ssl_module --with-mail --with-mail_ssl_module --with-file-aio --with-http_v2_module --with-cc-opt='-g -O2 -fstack-protector-strong -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2' --with-ld-opt='-Wl,-z,relro -Wl,--as-needed' --with-ipv6 

我也经历了很多docker挂起。 Docker会经常挂断几分钟或更长的时间，以至于我不得不重启这个盒子。 目前不完全确定如何debugging。

以下是对nginx容器的检查：
