Crontab and reboot command?

you should always use a absolute path in the cron for sure,

 

can you try typing

 

which full_box_reboot

 

to get the path of full box reboot.

 

 

Curious why your doing a monthly reboot? I've never seen these things have that kind of issue.

 

 

Also, are you running in a HA pair, are you interested in doing a config sync before you reboot your primary, unit to make sure the standby has the current config, I also would recommend creating a little shell script that would do a b verify load first - to make sure you have a valid config file before you reboot.
