實驗室的網頁伺服器主機
安裝的是Debian testing
有定期進行升級.
(包括安全性 deb http://security.debian.org/ testing/updates main contrib non-free)
但是apache 總有怪現象
top時 apache總是吃盡系統資源
我讓cron每天都重新啟動apache一次
重啟後會有大約一個小時左右的正常期
然後主機就又因apache滿載了
我有裝logwatch
以下是
其中一天的情形

覺得很奇怪的有
1.Errors when running cron:
bad mailto: 1229 Time(s)
2./var/spool/cron/crontabs/www-data 檔案內容為:
MAILTO=-C/tmp/sendmail.cf www-data

這樣的話
一天就要1440(24*60)次的ls
3.User www-data:

4.cron:
