紧急：SCO Unixware7.1.1 系统自动宕机

SCO unixware 7.1.1

操作系统多次在无操作的情况下宕机。查看系统日志/var/adm/syslog有如下信息：

请各位达人帮忙分析分析。小生有如下疑问：
1.系统宕机的原因是因为硬件故障呢还是系统的bug呢？
2.在这个时间点上（23:45:10），为什么每天都会有sendmail的信息，查看crontab无相关sendmail的信息。也无该时间点的任务
3.红色部分的PANIC: kernel-mode address fault on user address 0xB5F170DB是什么信息？是不是就是导致系统宕机的原因呢？
