我最近在我的VPS上安装了Nginx（已编译）+ PHP7-fpm + MariaDB！ 而我看到我所有的nginx /日志文件这个错误：
2017/11/17 17:45:15 [error] 23573#23573: *7 FastCGI sent in stderr: "PHP message: verify error, responseINVALID" while reading response header from upstream, client: 151.xxx.xxx.xxx, server: example.com, request: "GET /wp-admin/index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.1-example.sock:", host: "www.example.com", referrer: "https://www.example.com/wp-admin/index.php" 2017/11/17 17:45:18 [error] 23573#23573: *13 FastCGI sent in stderr: "PHP message: verify error, responseINVALID" while reading response header from upstream, client: 151.xxx.xxx.xxx, server: example.com, request: "POST /wp-admin/admin-ajax.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.1-example.sock:", host: "www.example.com", referrer: "https://www.example.com/wp-admin/index.php" 2017/11/17 17:46:18 [error] 23573#23573: *23 FastCGI sent in stderr: "PHP message: verify error, responseINVALID" while reading response header from upstream, client: 151.xxx.xxx.xxx, server: example.com, request: "POST /wp-admin/admin-ajax.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.1-example.sock:", host: "www.example.com", referrer: "https://www.example.com/wp-admin/index.php" 我的网站工作正常，但我在日志文件中看到此消息。 这个错误不重要，或者我的configuration文件有问题吗？ 这是我的虚拟主机文件的nginxconfiguration：

PS我的所有网站运行良好，只有这个错误出现在日志文件！
