你好，我遇到了 OOM killer 问题，导致：[mpm_prefork:error] [pid 18103] (12)无法分配内存：AH00159: fork: 无法分叉新进程
我必须重新启动服务器才能使其正常工作。
在 /var/log/messages 中靠近 OOM killer 消息的位置显示了正在运行的进程。
有140-160个httpd进程正在运行。
/etc/httpd/conf/httpd.conf 包括：
<IfModule prefork.c>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 100
ServerLimit 100
MaxRequestsPerChild 1000
</IfModule>
我认为这会将 httpd 进程的数量限制为 100？
