Channel error on connection - no exchange

[kevin]

hello,


I am using OpenStack Kilo version where rabbitmq is the default messaging service. Yesterday, our OpenStack Heat CLI did not work anymore and by investigation we found errors below in the rabbitmq log. Can somebody here help me? I am really new to RabbitMQ.

Thank you very much for your strong in advance.
