Strange RabbitMQ errors

[akalongman]

Versions:

• Laravel/Lumen version: 12.13.0
• RabbitMQ version: 3.9.21
• Package version: 14.2.0

I am getting strange errors and I dont know how to fix them. Even how to debug.

I have ran queue with supervisord:

[program:project-queue]
process_name=%(program_name)s_%(process_num)02d
command=php /var/www/project.ge/artisan queue:work --queue=queue1,queue2,queue3 --tries=3 --max-time=3600
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
user=project
numprocs=16
redirect_stderr=true
stdout_logfile=/var/www/project.ge/storage/logs/workers/queue.log
stopwaitsecs=3600

And in Sentry I have the following errors:

1. PhpAmqpLib\Exception\AMQPRuntimeException: Lost connection: Channel connection is closed.
2. PhpAmqpLib\Exception\AMQPProtocolChannelException: PRECONDITION_FAILED - delivery acknowledgement on channel 1 timed out. Timeout value used: 1800000 ms.
3. PhpAmqpLib\Exception\AMQPTimeoutException: The connection timed out after 3 sec while awaiting incoming data.

Queue Config:

'rabbitmq' => [
    'driver' => 'rabbitmq',
    'queue'  => env('RABBITMQ_QUEUE', 'default'),
    'hosts' => [
        [
            'host'     => env('RABBITMQ_HOST', '127.0.0.1'),
            'port'     => env('RABBITMQ_PORT', 5672),
            'user'     => env('RABBITMQ_USER', 'guest'),
            'password' => env('RABBITMQ_PASSWORD', 'guest'),
            'vhost'    => env('RABBITMQ_VHOST', '/'),
        ],
    ],
    'options' => [
        'queue' => [
            'job' => RabbitMQJob::class,
        ],
    ],
    'connection'   => RabbitMQConnection::class,
    /*
     * Set to "horizon" if you wish to use Laravel Horizon.
     */
    'worker'       => RabbitMQQueue::class,
    'after_commit' => true,
],

The content of the RabbitMQQueue:

<?php

declare(strict_types=1);

namespace App\Libraries\Queue;

use PhpAmqpLib\Channel\AMQPChannel;
use Throwable;
use VladimirYuldashev\LaravelQueueRabbitMQ\Queue\RabbitMQQueue as BaseRabbitMQQueue;

use function logger;

class RabbitMQQueue extends BaseRabbitMQQueue
{
    protected function publishBasic($msg, $exchange = '', $destination = '', $mandatory = false, $immediate = false, $ticket = null): void
    {
        try {
            parent::publishBasic($msg, $exchange, $destination, $mandatory, $immediate, $ticket);
        } catch (Throwable $throwable) {
            logger()->channel('queue')->warning('publishBasic: Exception occurred: ' . $throwable->getMessage() . '. Try to reconnect..');
            $this->reconnect();

            parent::publishBasic($msg, $exchange, $destination, $mandatory, $immediate, $ticket);
        }
    }

    protected function publishBatch($jobs, $data = '', $queue = null): void
    {
        try {
            parent::publishBatch($jobs, $data, $queue);
        } catch (Throwable $throwable) {
            logger()->channel('queue')->warning('publishBatch: Exception occurred: ' . $throwable->getMessage() . '. Try to reconnect..');
            $this->reconnect();

            parent::publishBatch($jobs, $data, $queue);
        }
    }

    protected function createChannel(): AMQPChannel
    {
        try {
            return parent::createChannel();
        } catch (Throwable $throwable) {
            logger()->channel('queue')->warning('createChannel: Exception occurred: ' . $throwable->getMessage() . '. Try to reconnect..');
            $this->reconnect();

            return parent::createChannel();
        }
    }
}

My current understanding of RabbitMQ is insufficient to determine the appropriate direction for further investigation.
