Looking at the trace, we can see that there are two connections with one 
channel each that create *lots* of consumers, all on the same two 
queues. More than 20,000 consumers in ~15 minutes.

These consumers are never cancelled; the client just keeps creating more 
and more of them.

You should be able to confirm this by looking at the consumer count in 
the management UI overview.

This looks like a bug in the application or client library, and explains 
why rabbit is consuming increasing amounts of memory, since each of 
these consumers requires some bookkeeping.
