[問題] 伺服器偶爾會重開機
我是centos 6.7
我確定沒有下排程去重開機，crontab裡面只有三項工作，兩項是把指定資料夾
內超過一個月的檔案清掉，還有一項是yum -y update。全部都是凌晨作業。
我最近一個月發生過兩次重開機，我原本以為有斷電或是power不穩，不過
查過message後發現應該是正常重開機，

這樣應該是有被下指定對吧？另外last也說
reboot system boot 2.6.32-573.18.1. Wed Mar 9 17:06 - 14:06 (3+20:59)
reboot system boot 2.6.32-573.18.1. Thu Mar 3 03:06 - 17:03 (6+13:57)
請問為什麼會重開？

起初，他們追殺共產主義者，我沒有說話，因為我不是共產主義者；
接著，他們追殺猶太人，我沒有說話，因為我不是猶太人；
後來，他們追殺工會成員，我沒有說話，因為我不是工會成員；
此後，他們追殺天主教徒，我沒有說話，因為我是新教教徒；
最後，他們奔我而來，卻再也沒有人站起來為我說話了。
