启动时间为 2007 年 02 月 10 日 9:32

删除2G的/var/log/httpd-access.log文件

启动时间为 2007 年 02 月 10 日 12:42再次自动重启

再次删除/var/log/httpd-access.log新文件，并取消httpd.conf的log/httpd-access.log配置选项。

现在仍然重启！

请大家帮们看看是什么地方出的问题？

llzqq

更换过内存吗，这个最容易有问题。另外机器负载是不是很大

llzqq

另外检查一下da0/da1

一片秋叶

刚装完的时候服务器连续运行一直很好，
内存一直没动过，负载不大，多数是在低负载时重启的，有时几个小时一次，有时10几个小时一次，一天总会重启几次，我怀疑是硬盘的问题！
有几次出现过Enter full pathname of shell or return for /bin /sh:

fsck －y
后来就没有了

check 一下 /var/log 下面的日志再说吧

HonestQiao

/var/log/message
尽快查看（死机重启之后）

原因是什么  等结果！！！！

晕
挖坟贴
不过我也想知道原因

是不是计划任务哈。

到底是硬件问题还是软件问题？解决了也不共享一下。freebsd系统维护起来好麻烦，可能是稳定性太好了，很少看到红魔维护的解决思路。
