Cron無故停止排程...
依序檢查相關設定

Step 1.check log

# cat /var/cron/log

Step 2.check cron file

#cat /var/spool/cron/crontabs/"username"

#chmod & chgrp

Step 3. Service  stop & start

# /etc/init.d/cron stop

# /etc/init.d/cron start

# ps -ef |grep cron

依續做完後，排程仍無動作...

再找不到好的解決方式，乾脆把/var/spool/cron/crontabs/"username"砍掉重建。

結果排程就正常執行了。

***備註***

在crontab設定vi編輯

$ which $EDITOR
$ 
$ EDITOR=vi
$ export EDITOR

在root下，設定"username"的排程指令
#crontab -e "username"
