nginx - php-fpm 一直是ESTABLISHED

这两天服务器上的php-fpm 一直很奇怪的被一个外部ip访问到我的php-fpm配置里做了ip限制 listen.allowed_clients = 127.0.0.1 但是他还是能连进来而且不是通过9000端口进来的整个进程一直被占用处于ESTABLISHED状态怎么回事是php-fpm有漏洞么该怎么查杀？为什么php-fpm本来监听的9000端口却通过其他端口连出去了

正常的连接是下面截图

web server和fastcgi之间是通过网络连接的啊
一段fastcgi listen 9000，另一端难道不要开端口吗？

因为nginx和php之间是长连接，一旦连接建立成功，就不需要再关闭了，然后两者就可以一直愉快的通信了啊。如果用完一次，就关闭一次，会凭空产生不必要的重连的时延。反正这个连接就只有nginx和php使用，不用担心连接数被耗尽;传统的http协议之所以要做成短连接，是由于web服务是在公网上使用，一个浏览器访问当前网站建立的socket连接如果长时间不释放，然后每个访问的浏览器都学他不释放，服务器连接数就会被耗尽。综上所述，就是长短连接之间的区别和用途了。

我现在已经知道是什么了那是php和memcache建立的长连接和nginx没关系请看清截图和问题链接是从php出去连外部的不是外部来连php谢谢
