当我使用 linux 时，为什么 laravel 上的 Jobs 会导致我的计算机崩溃？ 但是当我使用 Windows 时工作正常？

Question

I have been a laravel developer for 1 year already..Before I used laravel on Windows but since I use Linux..I have a Big problem on Jobs in laravel..every time I start a Job on linux my machine crashes.. but on windows everything works fine.

//my Controller

<?php

namespace App\Http\Controllers;
use App\Jobs\CustomerJob;

use Illuminate\Http\Request;

class SendEmailControllers extends Controller
{
public function sendEmail(){
    dispatch(new CustomerJob())->delay(now()->addMinutes(1));
    dd('Email has been delivered');
}

}

//Job Code

<?php

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldBeUnique;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\Mail;
use App\Mail\WelcomeUserMail;

class CustomerJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable,   SerializesModels;

/**
 * Create a new job instance.
 *
 * @return void
 */
public function __construct()
{
    //
}

/**
 * Execute the job.
 *
 * @return void
 */
public function handle()
{
    Mail::to('bramslevel129@gmail.com')->send(new WelcomeUserMail);
}

}

Here is the error that is displayed when I restart the machine. the error is displayed on my Failed_job table..

//error

Illuminate\Queue\MaxAttemptsExceededException:

Answer 1

try set breaking rules for job to stop hanging your system

//CustomerJob.php
    /**
     * The number of seconds the job can run before timing out.
     *
     * @var int
     */
    public $timeout = 15; // just for your case

    /**
     * Indicate if the job should be marked as failed on timeout.
     *
     * @var bool
     */
    public $failOnTimeout = true;


    /**
     * The number of times the job may be attempted.
     *
     * @var int
     */
    public $tries = 3;
 
    /**
     * The maximum number of unhandled exceptions to allow before failing.
     *
     * @var int
     */
    public $maxExceptions = 1;

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        Log::debug('jobs', ['job start']);
        Mail::to('bramslevel129@gmail.com')->send(new WelcomeUserMail);
        Log::debug('jobs', ['job end']);
    }

and check project_folder/storage/logs/laravel.log (if log configured as single file) or corresponding with log config - there can be errors regarding job itself not (failed to send mail because of bad mail config for example)

---

step 2: try set mail driver to log to see changes and again check logs

# .env file
# you can comment lines using # in this file
# MAIL_MAILER=smtp
MAIL_MAILER=log
MAIL_LOG_CHANNEL=debug
