Количество процессов httpd и prefork.c

Привет, у меня проблемы с убийцей OOM, которые вызвали: [mpm_prefork: error] [pid 18103] (12) Невозможно выделить память: AH00159: fork: Невозможно выполнить форк нового процесса

Мне пришлось перезапустить сервер, чтобы он заработал.

В / var / log / messages рядом с сообщения-убийцы OOM он показал запущенные процессы.

Было запущено 140-160 процессов httpd.

/etc/httpd/conf/httpd.conf включает:

<IfModule prefork.c>
    StartServers          5
    MinSpareServers       5
    MaxSpareServers       10
    MaxClients            100
    ServerLimit           100
    MaxRequestsPerChild   1000
</IfModule>

Я думал, что это ограничит количество процессов httpd до 100?
