Just to add to what Joe said, in the screenshot the queue that you’re listing shows that blue load balancing icon, meaning that it is actively load balancing. The listing will not include any FlowFiles that are queued up to move to another node. So on a connection like that where it’s actively load balancing you may not be able to view the contents.

MergeContent is a common processor that would do this but others certainly can. What processor do you have there? If you stop the target processor then delete it should always work though you generally should not need to do so but normally deleting queue content is a debug thing so you can.

Occasionally, I will see a queue showing queued messages, but when I list the queue, the UI says that there are no flow files. Also the consumer of this queue seems to be idle. I can then empty the queue and it reports that n messages were deleted. Any idea what is happening here? <QGIOIT37jHpHzA5e.png> <ZDDoxeQhEFQdJezH.png> -Joe [https://s-install.avcdn.net/ipm/preview/icons/icon-envelope-tick-green-avg-v1.png]<http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> Virus-free.www.avg.com<http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> <x-msg://22/#m_5948377795112736779_DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
