> What do netstat -m and vmstat -m show ?
# netstat -m
341 mbufs in use:
329 mbufs allocated to data
6 mbufs allocated to packet headers
6 mbufs allocated to socket names and addresses
0 calls to protocol drain routines
# netstat -m
354 mbufs in use:
342 mbufs allocated to data
6 mbufs allocated to packet headers
6 mbufs allocated to socket names and addresses
0 calls to protocol drain routines
# netstat -m
359 mbufs in use:
347 mbufs allocated to data
6 mbufs allocated to packet headers
6 mbufs allocated to socket names and addresses
0 calls to protocol drain routines
# netstat -m
365 mbufs in use:
353 mbufs allocated to data
6 mbufs allocated to packet headers
6 mbufs allocated to socket names and addresses
0 calls to protocol drain routines
So more and more mbufs are allocated by then.
# vmstat -m
