Once allocated from the map, they are allocated and freed from a private pool. NMBCLUSTERS determines the size of the map and thus the maximum number that can be allocated from it. The number of clusters currently in-use and in the free pool is what netstat -m reports, and the total of these thus indicates the peak in-use amount. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
