Increasing Memory Usage

[flute]

I'm using Nginx 0.7.61 with php-fpm(php 5.2.6) on Freebsd7.1-amd64。
When i  starte nginx,the total memory usage beging Increase. Unitl used all memory.
use top with sort size,i'm look at the each nginx work process used more than 400M memory.
The solution is used 'kill -HUP'
