조치사항

<IfModule mpm_worker_module>
ServerLimit 64
StartServers 64

주의사항

MaxRequestWorkers 설정값을 올려줘야 하는데
그냥 무심코 올리면 이런식으로 경고가 발생한다

AH00316: WARNING: MaxRequestWorkers of 512 is not an integer multiple of
ThreadsPerChild of 25, decreasing to nearest multiple 500,
for a maximum of 20 servers.
AH00318: WARNING: MaxRequestWorkers of 500 would require 20 servers and
would exceed ServerLimit of 16, decreasing to 400.
To increase, please see the ServerLimit directive.

AH00316 : ThreadsPerChild 수치의 배수가 되게끔 설정해라
AH00318 : MaxRequestWorkers의 수치를 ThreadsPerChild의 수치로 나눈 몫이 ServerLimit의 수치보다 높아서는 안된다
ServerLimit 를 따로 설정하지 않은 경우 기본값 : 16
