Laravel scheduler strange behavior in prod server

Question

The scheduler is running at strange times, I have config a task to run every minute and locally runs OK, but in prod server runs like repeated at some times.

This is my Kernel.php code

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel
{

    protected $commands = [];


    protected function schedule(Schedule $schedule)
    {

        $schedule->call(function () {
            return true;
        })->everyMinute()->emailOutputTo('...')->thenPing('...');

    }

    protected function commands()
    {
        $this->load(__DIR__.'/Commands');

        require base_path('routes/console.php');
    }


}

The execution output I get from the prod server:

19.06
19.07
19.08
19.09
19.10
19.11
19.12
19.13
19.16
19.16
19.16
19.17
19.18
19.21
19.21
19.21
19.22
19.23
19.25
19.25
19.26

Any ideas?

Looking at the output it seems it's running every minute, but sometimes it takes more time to execute the task and probably you save time after finishing the job, so for example:

19.12 -> was started at 19:12 and finished at 19:12
19.13 -> was started at 19:13 and finished at 19:13
19.16 -> was started at 19:14 and finished at 19:16
19.16 -> was started at 19:15 and finished at 19:16
19.16 -> was started at 19:16 and finished at 19:16
19.17 -> was started at 19:17 and finished at 19:17
