   Mbuf clusters are never freed back to the global free memory pool. If your
machine doesn't have much memory and the number of clusters that get allocated
is large, then there won't be much left for user processes and the machine
will thrash or worse. You have to have the memory resources if you want to
handle high networking loads.
