死机和lo: Disabled Privacy Extensions和__ratelimit: 1 callbacks suppressed的问题

服务器上线3天左右,ubuntu9.10,i386版本,升技848主板,CD2.4,512M,GF4显卡,SATA硬盘.
用的desktop版,但是kernel加了text参数启动,没用图形界面.apt安装了apache,php5,vsftpd,ssh,另外手动安装了mysql
启动了iptables的NAT功能
目前提供NAT,Web服务,流量很小,应该说负荷轻
昨天晚上死了一次机,今天凌晨4点竟然也死了一次.
我现在观察message,倒看不出记录,但是看到这两天很多这样的记录

我分析了这几天的日志,发觉,只有最初装系统时没有lo: Disabled Privacy Extensions的提示,正式上线后都有.
那正式上线有原来有什么不同呢?我想了想,只有一点不同,就是外网的网卡IP变了,NAT脚本中原来是指定了新外网IP,也就是说原来NAT没真正起作用,尽管用iptables -n -L -t nat也能看到..
但是,iptables的模块不应该会出错吧?

不过,死机并不一定是上面的问题...
