rabbimq operation queue.declare caused a channel exception not_found

問題

操作 openstack 的 horizon，刪除，或者新建雲主機，一直卡住，最後報錯接收消息超時，參看 rabbitmq 日誌，發現如下報錯:

=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

經查詢，是隊列 versioned_notifications.info 有問題，去 rabbitmq management 頁面查看，發現該隊列的各項數據均顯示 NaN, 而正常的隊列都有數據，即使沒有消息，也會顯示爲 0

解決

根據 https://github.com/rabbitmq/rabbitmq-server/issues/1333 操作，刪除該隊列

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

之後再操作horizon, 問題解決，rabbitmq management 頁面也顯示正常
