I seem to be having errors with FBSD = and internet=20 resources. I can access so many internet applications at a time = and then=20 it will just start dropping them off with "no buffer space available=20 errors" I have this occurring on two boxes at the current = moment. =20 One is a dialup and the other is connected to a T1.

I will refer to the home box in this = article. =20 It is a p200 with 64 meg of ram and an 800 meg hdd. It is running = FBSD=20 3.4 - RELEASE

root@cookies:/usr/home/trey# netstat -m =

150/288 mbufs in=20 use:
135 mbufs allocated = to=20 data
15 mbufs allocated to = packet=20 headers
32/46/8192 mbuf clusters in use (current/peak/max)
128 = Kbytes=20 allocated to network (64% in use)
0 requests for memory denied
0 = requests=20 for memory delayed
0 calls to protocol drain=20 routines
root@cookies:/usr/home/trey#

I increased the mbufclusters in = the=20 kernel

options =20 NMBCLUSTERS=3D8192

I also increased the maxusers to = 128

one computer runs DLINK nic and = the other has=20 an SMC nic

Any suggestions would be MUCH=20 appreciated.
