<p>Hi :</p>
<p> When I use RabbitMQ "Presence Exchange" Plugin, I found when a client (name:"Client_1") bind to the x-presence exchange, the queue (name:"monitor_queue") with "" route key can get a "bind" msg, but if I didn't subscribe the queue("Client_1") with a process,
when the "client_1" coredown, the "monitor_queue" can not get a "unbind" msg. If I subcribe the queue("client_1"), when "client_1" coredown or exit, the monitor_queue can got a "unbind" msg.</p>
<p> My question is: I have bind the queue("client_1") to the exchange("monitor"), why can not got the "unbind" msg when queue("client_1") not be subscribed, but can got the "unbind" msg when queue("client_1") be subscribed.</p>
<p> </p>
<p>Regards,<br>
David</p>
