  Yes, messages keep piling up and memory usage keeps increasing until the Erlang VM goes out of memory. To debug, there's a max_heap_size parameter which can be configured to log an error message when heap size of any process goes beyond a threshold, or it can even kill the process[0]. Although I don't know if this takes the "off-heap" messages into account. Also, there are lots of libraries which can provide a "top" like view of the running system.
