关机调用关闭数据库服务导致重启原因，请帮忙。

思路：查看以下文件
1、cat /var/log/messages
2、cat /var/log/secure
3、history
4、cat /var/log/acpid

系统是在今天早上04:01:47重启的；
/var/log/messages临近记录：

history没有临近可以命令；

cat /var/log/acpid   ----  这个日志就有点可疑了：

注意看/var/log/acpid 这个文件尾部：Thu Mar 18 16:34:52 启动之后没有正常的exiting日志就接到今天早上4点的starting up；
昨天下午我设了一个服务，功能是在计算机重启或关机之前关闭数据库，以下是我的操作：
1：脚本文件
/etc/init.d/OS_halt_onmodeDB：
很简单，就是设置下环境然后执行关闭数据库命令；
2：创建链接
ln -s /etc/init.d/OS_halt_onmodeDB /etc/rc.d/rc0.d/K00OS_halt_onmodeDB
ln -s /etc/init.d/OS_halt_onmodeDB /etc/rc.d/rc5.d/K00OS_halt_onmodeDB
3：在/etc/rc.local添加：
touch /var/lock/subsys/OS_halt_onmodeDB

；；；
按/var/log/acpid这个文件来看是系统在上一次关机时没有正常结束导致重启，上一次的重启花了8分多钟，平时只要4分钟就起来的；
/etc/init.d/OS_halt_onmodeDB这个脚本我用root执行时是很顺利的，目前这机器还没开始用，数据库是空的，排除关闭数据库失败，所以我怀疑是我做服务的步骤有问题；
