问题一 由ZMD服务器引起，Novell对ZMD服务的解释为：
The zmd daemon performs software management functions on the ZENworks managed device, including updating, installing, and removing software, and performing basic queries of the device's package management database. Typically, these management tasks are initiated through the ZENworks Control Center or the rug, zen-installer, zen-updater, or zen-remover utilities, which means you should not need to interact directly with zmd.
ZMD服务主要负责用户软件的更新、安装管理操作，在开机时自动启动，ZMD服务启动后，默认每六小时联网更新，更新时会占用80端口，因此经常会与tomcat 等服务器产生端口，因此在软件安装或更新完后，可以及时关闭此服务，
#/etc/init.d/novell-zmd status
Checking for ZENworks Management Daemon: running
#/etc/init.d/novell-zmd stop
Shutting down ZENworks Management Daemon done
注：关闭 此服务后，安装软件是比较麻烦，因此在需要时可以在此打开，改服务在更新时有可能会长时间锁定/etc/mtab，因此需要注意。
解决方法：
关闭novell-zmd服务后，此日志消失。
有时我们为了提高开机速度，会将novell-zmd服务进行关闭
chkconfig -delete novell-zmd
问题二：
单从日志信息上看cpu不支持变频的问题，由于在操作系统和VCS日志中均没有发现其他异常，因此怀疑是服务器硬件出了问题，去机房一看，服务器住面板有电流符号的故障灯显示橘红色，这时基本就能放松了，硬件肯定是不对了，于是收集硬件日志联系HP厂商，经确定是主板故障，更换主板后，服务器没有重启。
