网络服务器无响应

Question

我需要一些有关我们正在运行的新 Apache2.4 和 PHP-FPM 服务器的帮助。网站偶尔会变得无响应。我们刚刚转移到 PHP-FPM，旧服务器没有这个问题。

Checking the FPM log we're getting a lot of the following errors just before the site goes unresponsive
WARNING: pid 2897506, fpm_request_check_timed_out(), line 265: [pool www] child 3752421, script 'FILE PATH  Executing too slow

有人能指出我正确的方向吗？FPM 对我来说是一个新概念，我想确保我已正确配置它。
