Why does laravel 8 scheduler build crash "Warning: Error reading communication packets"?

[ghost]

There is a scheduler that every 5 seconds gets the message history of each client from the telegram.
I use supervisorctl to start.

[program:short-scheduler]
command=/usr/bin/php /var/www/messenger/new_api/artisan short-schedule:run
numprocs=1
autostart=true
autorestart=true

This artisan short-schedule:run command runs the code:

protected function shortSchedule(ShortSchedule $schedule) {
        $schedule->command('telegram:history')->everySecond(5)->withoutOverlapping();
    }

And when I run the sudo supervisorctl stop short-scheduler command, then every 5 seconds a message pops up in the console:
Feb 26 13:17:32 messenger mariadbd[890306]: 2022-02-26 13:17:32 179 [Warning] Aborted connection N to db: 'test' user: 'test' host: 'localhost' (Got an error reading communication packets)

PS All executions in the created scheduler have been removed and processed. So it's definitely not a bug in the code.
