nagios加ndo监控563台机器，5066个服务，监控时间不更新
请教哪位大虾，小弟是搞开发的，最近由于项目需要让我搞nagios监控，一时摸不着头脑，情况如下：

nagios版本:3.0.6

有563台机器，5066个服务需要监控，机器分别在192.168.33.0,192.168.34.0,192.168.35.0,192.168.36.0,192.168.38.0,192.168.39.0
这几个网段，个网段之间应该是用的路由器转发的，采用的是nagios的nrpe主动监控方式，开始是没加ndo转存的，监控记录如下：

------------------------
未加转存：
begin: Thu Sep 30 14:39:15 CST 2010
middle: Thu Sep 30 15:01:51 CST 2010(初始化服务和主机监控)
over: Thu Sep 30 15:13:51 CST 2010(主机监控轮询一次)

down机测试(29-1 192.168.35.2加防火墙禁ping)
begin: Thu Sep 30 15:18:35 CST 2010
over: Thu Sep 30 15:28:15 CST 2010
------------------------

但是加了转存以后一直卡住，nagios页面上的Last check时间一直没变，底下是日志信息：

------------------------

加了ndo以后最一行日志一直是那样并没有更新。

nagios.cfg主要配置如下：
------------------------
status_update_interval=10
nagios_user=nagios
nagios_group=nagios
check_external_commands=0

最后申明一下，小弟我以前是搞java开发的，对linux只是略微熟悉，C语言懂的更少了，麻烦各位大虾能帮帮我，上面的经理压的紧，都快两个星期了，还是没搞定，谢谢
