I have many queue, each queue will export 1 pdf file
Sometimes I get error in laravel log

Allowed memory size of 134217728 bytes exhausted ...

After investigation it seems the cause is memory leak
I tried to reproduce it as follows

Environment

  • laravel/framework: v10.41.0
  • barryvdh/laravel-snappy: v1.0.2
  • h4cc/wkhtmltoimage-amd64: 0.12.4
  • h4cc/wkhtmltopdf-amd64: 0.12.4

Queue job

<?php

namespace App\Jobs;

use Barryvdh\Snappy\Facades\SnappyPdf;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\Log;

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

    /**
     * Create a new job instance.
     */
    public function __construct()
    {
        $this->onConnection('database');
    }

    /**
     * Execute the job.
     */
    public function handle(): void
    {
        Log::info('--------------------------------');
        Log::info('Start: '.(memory_get_usage() / 1024));
        $snappy = SnappyPdf::loadHTML('<div>Something</div>');
        // unset($snappy);
        // gc_collect_cycles();
    }
}

Start memory is continuously increasing until it exceeds the limit
