Let's say the main RabbitMQ log has the following.

NOT_FOUND – no exchange 'exchange001' in vhost 'vhost001'

This event may appear if there is a shovel in a "terminated" state. The rabbitmqctl shovel_status command can be used to determine if there are any shovels in a terminated state.

rabbitmqctl shovel_status

If there is a shovel in a terminated state, something like this should be returned.

                                   <<"NOT_FOUND - no exchange 'exchange001' in vhost 'vhost001'">>}},
 {gen_server,call,
             [<11597.12815.21>,
              {call,{'queue.bind',0,<<>>,
                                  <<"exchange001">>,
                                  <<"#">>,false,[]},
                    none,<11597.12806.21>},
              60000]}}  dynamic foo

In this scenario, the rabbitmqctl delete_shovel command can be used to delete the shovel in a terminated state.

rabbitmqctl delete_shovel -p vhost001 shovel001
