rabbimq operation queue.declare caused a channel exception not_found

问题

操作 openstack 的 horizon，删除，或者新建云主机，一直卡住，最后报错接收消息超时，参看 rabbitmq 日志，发现如下报错:

=ERROR REPORT==== 29-Feb-2020::15:01:26 ===
Channel error on connection <0.21564.0> (10.0.10.15:40582 -> 10.0.10.11:5672, vhost: '/', user: 'openstack'), channel 1:
operation queue.declare caused a channel exception not_found: failed to perform operation on queue 'versioned_notifications.info' in vhost '/' due to timeout

经查询，是队列 versioned_notifications.info 有问题，去 rabbitmq management 页面查看，发现该队列的各项数据均显示 NaN, 而正常的队列都有数据，即使没有消息，也会显示为 0

解决

根据 https://github.com/rabbitmq/rabbitmq-server/issues/1333 操作，删除该队列

rabbitmqctl eval 'rabbit_amqqueue:internal_delete({resource,<<"/">>,queue,<<"versioned_notifications.info">>}).'

之后再操作horizon, 问题解决，rabbitmq management 页面也显示正常
