issue with queue priority on RabbitMqBundle - symfony

Question

I am trying to setup a priority queue. Without priority, it is working just fine but I need to prioritize messages.
I am using RabbitMqBundle 1.14 and rabbitmq-supervisor-bundle 3.1 with RabbitMQ 3.5.7 (Erlang 18.3)
Here is the config.yml :
old_sound_rabbit_mq:
connections:
default:
host: '127.0.0.1'
port: 5672
user: 'xxx'
password: 'xxx'
vhost: '/'
lazy: false
connection_timeout: 3
read_write_timeout: 3
# requires php-amqplib v2.4.1+ and PHP5.4+
keepalive: false
# requires php-amqplib v2.4.1+
heartbeat: 0
#requires php_sockets.dll
use_socket: true # default false
producers:
global:
connection: default
exchange_options: {name: 'global', type: direct}
queue_options:
name: global
consumers:
global:
connection: default
exchange_options: {name: 'global', type: direct}
queue_options: {name: 'global', arguments: {'x-max-priority': ['I', 10]} }
callback: rabbitmq_simu_service
And the message sent to queue :
$msg = array();
$msg['id'] = $id;
$msg['action'] = 'simu';
$additionalProperties = ['priority' => 4] ;
$routing_key = '';
$this->container->get('old_sound_rabbit_mq.global_producer')->publish(serialize($msg), $routing_key , $additionalProperties);
I get the following error when sending the message :
PRECONDITION_FAILED - inequivalent arg 'x-max-priority' for queue 'global' in vhost '/': received none but current is the value '10' of type 'signedint'
I also tried in the config.yml :
queue_options: {name: 'global', arguments: {'x-max-priority': 10} }
In this case, I got no error but messages are not consumed.
Does anyone know how to send priority message ?

Answer 1

The message you have received is the error message for what happens when you try to create a queue, but the queue already exists with different parameters. You must delete the queue first, then try running your program.

Answer 2

PRECONDITION_FAILED - inequivalent arg 'x-max-priority' for queue 'global' in vhost '/': received none but current is the value '10' of type 'signedint'
That message means that you have already created the global queue with a max priority of 10, but something else is trying to declare it with no priority. You must review your code for both your producer and consumer to ensure that if they declare this priority queue they use exactly the same x-max-priority argument.
