[rabbitmq-discuss] When I declared mirrored queues using spring-rabbit API, one of them is sometimes failed.

[Min Cha]

Hi all.
First of all, thanks for rabbitmq team & community. With rabbitmq, our
production environment has been improving.
I am very pleased if you help me.

*Environment*

1. rabbit-mq 2.8.4(and java client 2.8.4), spring-amqp 1.1.0, spring-rabbit
1.1.0.
2. erlang RB15B01

*Problem*

1. When I declared mirrored queues using spring-rabbit API, one of them is
sometimes failed.
2. As a result, the failed queue(s) does not exist.
3. When I rerun my code without any changes, it is sometimes success.
4. Code for declaring the queues is as following.

*<bean id="notificationAddCommentQueue"
class="org.springframework.amqp.core.Queue">*
* <constructor-arg name="name" value="cafe.notification.addComment" />*
* <constructor-arg name="autoDelete" value="false" />*
* <constructor-arg name="exclusive" value="false" />*
* <constructor-arg name="durable" value="true" />*
* <constructor-arg name="arguments">*
* <map>*
* <entry key="x-ha-policy" value="all" />*
* </map>*
* </constructor-arg>*
*</bean>*
*
*
*...*

*for (Queue queue : queues) {*
*  rabbitAdmin.deleteQueue(queue.getName());*
*  rabbitAdmin.declareQueue(queue);*
*}*

5. Error logs on rabbitmq-server is as following.
