原因：
工人> 0会有很多线程在端口8069上。
你也会有几个cron线程8069(max-cron-threads)。
一个gevent线程在端口8072上(longpolling-port)。
这里的问题就在8072上，web会用8069请求longpolling。所以http出错。
解决方法：
安装返向代理，用http://host:80代理 http://localhost:8069/ 和 http://localhost:8072/longpolling即可
如nginx配置
location / {
proxy_pass http://localhost:8069/;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location /longpolling/ {
proxy_pass http://localhost:8072/longpolling/;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
