Issue with multiple consumers - re-delivering in progress jobs

Hello,

I'm not sure if I have found a bug or if this just a case of user error.

I am having an issue with running multiple workers on long running jobs (~20 minutes).

When add a message into the queue and then start 2 workers using the following command
bin/cake worker -c process-invoices -p process-invoices

Initially, 1 worker will begin to process the job. However, after about 5 minutes, the other worker also begins to start working on the same job.

I have set $maxAttempts = 1 in the job class.

Next, I tried to bind each processor to an unique name
bin/cake worker -c process-invoices -p process-invoices1
and
bin/cake worker -c process-invoices -p process-invoices2

The message is only picked up by 1 worker, however if another message gets added to the queue, the other worker receives the following error:

[LogicException] Processor was not found. processorName: "process-invoices2" in /var/www/html/vendor/enqueue/enqueue/ArrayProcessorRegistry.php on line 33

And when I don't bind the processor name and run the following command twice to create 2 workers
bin/cake worker -c process-invoices

I receive a similar error:

error: [LogicException] Processor was not found. processorName: "Cake\Queue\Queue\Processor63e2a1884f1c4" in /var/www/html/vendor/enqueue/enqueue/ArrayProcessorRegistry.php on line 33

For reference, the config for the queue is:

'Queue' => [
    'process-invoices' => [
        'url' => null,
        'queue' => 'process-invoices',
        'logger' => 'stdout',
        'receiveTimeout' => 10000,
        'storeFailedJobs' => true,
    ],
],

I am unable to figure out a method of having multiple workers without the errors or re-processing jobs.
Is there any config setting (visibility timeout) that I am missing to resolve my issues?

Thanks!

Beginne damit, das Problem mit zwei bin/cake-Worker-Prozessen unter Verwendung der process-invoices-Konfiguration und eines lang laufenden Jobs zu reproduzieren. Lies den Worker-Einstiegspunkt und den gemeldeten Fehler in ArrayProcessorRegistry.php und vergleiche anschließend das Verhalten mit eindeutigen und gemeinsam genutzten Prozessornamen. Als abgeschlossen gilt, dass mehrere Worker wartende Jobs ohne erneute Zustellung oder Processor was not found-Fehler verarbeiten können.
