This has been discussed several times before. Here's what I don't understa=
nd.
The output of netstat -m:
# netstat -m
178/288/131068 mbufs in use (current/peak/max):
178 mbufs allocated to data
177/278/32767 mbuf clusters in use (current/peak/max)
628 Kbytes allocated to network (0% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
Now my config file has the following lines:
maxusers 512
options NMBCLUSTERS=3D32767
options NMBUFS=3D131068
And the output of netstat is:
# netstat
