Bugs in Cronjob Setting

I have set the below cronjob in cronjob editor using


php -q “/home/jamal1234/web/demo.abc.info/public_html/cron.php” >/dev/null 2>&1

It works for a while and then stop working.
After some time or even 5 minutes it stop working.
I am facing this problem from the new update of Hestia I think.
Any Solution Please?
