I just found out about netstat -m, but I don't understand some of it's output. Can somebody explain me what is "mbuf+clusters out of packet secondary zone in use" ? My output shows it raised significantly during equilibrium after several stress runs: BEFORE 16641/217734/234375 mbufs in use (current/cache/total) 16640/217766/234406/262144 mbuf clusters in use (current/cache/total/max) 256/1664 mbuf+clusters out of packet secondary zone in use (current/cache) AFTER 625083/86562/711645 mbufs in use (current/cache/total) 180264/81880/262144/262144 mbuf clusters in use (current/cache/total/max) 160420/311 mbuf+clusters out of packet secondary zone in use (current/cache) Thanks Yony
