Cron does not work

Cron does not work

I read the documentation. I know that it resides in memory, but when I use
crontab -e, it should update the cronjob file as well as reload the new cronjob
into the memory, effectively overwritting the previous one.

When I try it in another of my machine (with same OS version), it works
perfectly. So I don't think you're suppose to restart the crond program
everytime.

 ..in memory. You need to restart crond after editing the file that crontab
 executes unless crontab had been modified. This is all covered in man
 cron.
