That's a bug. It's quite difficult to trigger, so I'm not surprised it's 
taking a while for your broker to run into it.

AFAICT the bug will only surface on a channel with basic.qos prefetch, 
when there is a sequence of several basic.consume and basic.cancel 
commands involving the same queue. And there are several other 
conditions that need to be met, and the timing needs to be just right.

A workaround until we fix this would be closing channels after 
basic.cancel and using a fresh channel for every basic.consume.

Thanks for reporting this!
