环境是windows server 2008 + apache2.4 php5.6

apache会时不时的无法访问，错误日志如上，指定的网络名不在可用错误，我在httpd.conf里添加了下面两行：
AcceptFilter http None
AcceptFilter https None
重启apache之后，发现cpu占用明显增多，原来是10%不到，现在是30-40%，不知道是否有效果。

还有就是[Fri Aug 23 17:01:25.490119 2019] [fcgid:warn] [pid 3484:tid 584] mod_fcgid: process 6992 graceful kill fail, sending SIGKILL
这个错误咋搞，如何解决呢？

求指导
