Forge Horizon Daemon Fail Notice

Hi, Sometimes my horizon daemon fails due to lack of ram memory with error of

daemon-37304                     FATAL     Exited too quickly (process log may have details) 

and when it fails.

After restarting in forge panel it normally runs. So tried to simulate the restart of the deamon by terminating horizon. I check the status of horizon in App\Console\Kernel.php and when it fails I run

    shell_exec("cd /home/forge/my_domain.com && php artisan horizon:terminate");

this command. But the it doesn't works. How can I simulate restart daemon in forge's panel. Thanks in advance.
