关于solaris系统文件中的maxusers

   前几天重新启动服务器后，出现僵尸进程。经过查找终于发现是在/etc/system文件中有个变量maxusers设置为5。在网上搜索说是设置了远程登陆的机器数量，后来发现这个设置有问题。经过苦苦搜索发现了maxusers的解释如下：

The maxusers variable has nothing to do with the number of
user allowed on a system. It's one big knob that scales a number
of other parameters simultaneously. The standard settings and
derivations are more or less as follows, using /etc/system syntax:

* The big knob, scales automatically
set maxusers =

* Maximum number of allowable processes; currently at most 30000
set max_nprocs = 10 + 16 * maxusers

* Max processes per user (5 are reserved for the super user)
set maxuprc = max_nprocs - 5;

* Number of quota structures (need one per user per filesystem
* w/ quotas)
set ndquot = maxusers * NMOUNT / 4 + max_nprocs

* Maximum size of the directory name lookup cache (DNLC)
set ncsize = 4 * (max_nprocs + maxusers) + 320
set ufs_ninode = ncsize

注释掉maxusers的设置后系统僵死进程消失。所以，大家在设置这个参数时一定要注意三个参数一起设置，否则重新启动机器后系统文件生效系统可能就会有问题。
