我的网络服务器每隔 1-2 天就会达到无法访问的状态，直到我完全重新启动服务器。
服务器是 Debian Bullseye，配备最新的 Apache + PHP 7.4。我使用 FPM，因为我想要 HTTP2。16 GB RAM vServer。
/var/log/apache2/error.log：
[Sat May 07 18:01:57.970776 2022] [proxy_fcgi:error] [pid 139033:tid 139719866291968] (70007)The timeout specified has expired: [client xxxIPxxx:47330] AH01075: Error dispatching request to : (polling)

当然，我发现了有关此问题的不同帖子/解决方案，并且我已经增加了 PHP 和 FPM 的超时时间，但这个错误仍然存在。

我怎么解决这个问题？
非常感谢。
答案1
我遇到了同样的问题，可以通过创建来解决它/etc/httpd/conf.modules.d/00-proxy_timeout.conf。
作为内容尝试添加
Timeout xx
ProxyTimeout xx
将 xx 替换为适合您用例的秒数。只需尝试一下这些数字，看看它是否可以解决您的问题。
看一眼本指南。
