Thanks for the link!
So the publishing rate drops to zero, because Erlang RAM usage goes over
the limit of vm_memory_high_watermark (in my case, 3GB).
Then my question is: is it normal that 100 million persisted messages use 3
GB of memory? Shouldn't broker page them to disk and free memory? After I
hit the limit I waited for an hour, and memory usage didn't go down and
connections remained blocked.
