Question

我不是nginx服务器和fpm的专家，我突然多次出现此错误，但我无法确定导致此问题的原因：

我在服务器上运行

Intel Xeon D - 32 GB RAM - 2 x2TB RAID SOFT - 连接速度1 Gbps

 2017/12/06 23:37:58 [error] 20819#20819: *1 connect() to 

unix:/run/php/php7.0-fpm.sock failed (11: Resource temporarily unavailable) 
while connecting to upstream, client: 62.33.147.332, server: domainname.com, request: "POST /checkstatus HTTP/2.0", upstream: "fastcgi://unix:/run/php/php7.0-fpm.sock:", host: "domainname.com", referrer: "https://domainname.com/adminpanel/live"

这是我的nginx配置文件：

我尝试了以下解决方案，但没有奏效。 https://stackoverflow.com/a/10470827/2873860

对我的服务器的任何请求都将返回502 Bad Gateway

这是php-fpm7 log

当我重新启动fpm时网站重新启动而没有任何错误：

systemctl restart php7.0-fpm.service

但是一旦我访问了我的网页

https://mydomainname.com/live.php

如何使用一些连接到套接字的javascript代码的php会导致整个服务器崩溃？有可能吗？

服务器关闭，错误502

nginx [错误] 20819＃20819：* 1连接（）到unix：/run/php/php7.0-fpm.sock失败（11：资源暂时不可用）
