关于php-cgi的问题 求教军哥

cfan365

文件 /usr/local/php/etc/php-fpm.conf 里面 配置<value name="max_children">24</value>
可是进程里面有50个php-cgi啊！不是应该是24个吗？
执行这个
[root@localhost logs]# total=0; ii=0; for i in `ps -C php-cgi -o rss=`; do total=$(($total+$i)); ii=$(($ii+1));echo $ii; echo $i; done; echo "PHP-CGI Memory usage: $total kb"
