I have a 2-node cluster setup.<div><br></div><div>In the Queues tab, I see this in on one the queue.</div><div><div><br></div><div><img id="0feed01a-c50b-4cca-87ae-1bd83d0a206b" height="29" width="733" apple-width="yes" apple-height="yes" src="cid:CCA7EAFC-741F-4A52-A297-03961DE6E85F"></div></div><div><br></div><div>But when I click on this queue, I would see this.</div><div><br></div><div><img id="10130391-3b72-4906-a081-548ab3996b50" height="104" width="868" apple-width="yes" apple-height="yes" src="cid:E194348F-F541-4873-8127-A287E1FFAE26"></div><div><br></div><div>Then when I publish a message to this queue, it would get consumed and everything would go back to 0. There is nothing in the logs or sasl.log about this. So, I am wondering what this is. Also, this issue did not exist in RabbitMQ 2.8.7.</div><div><br></div><div>I was able to reproduce this issue. It looks like when the queue gets idle (eg. no message is sent/consumed) for exactly 1 hour, it changes from 0 to '?'.</div><div><br></div><div>Here is how to reproduce this.</div><div><br></div><div>1. Create a queue either through the UI or an ampq client (I used the pika python module).</div><div>2. Publish one message to the queue.</div><div>3. Wait for 1 hour then you will see the message go from 0 to '?'.</div><div>4. If you publish another message to this queue, it will go back to 0 again.</div><div><br></div><div><br></div><div>Thanks,</div><div>Jonathan</div></body></html>
