It turns out that I was running the broker using 32 bit binary, that is why the
memory limit is 40% * 4GB = 1.6 GB. the broker would crash if there are more
than 50 GB of messages in 1000 queues. When this happened, the memory usage
reached 4 GB.
If I run the broker using 64 bit, it does not crash because it could get more
than 6 GB of memory. It was able to consume all the messages at rate of
100-200 MB/sec.
Thanks.
