I seem to be having errors with FBSD and internet resources. I can access so many internet applications at a time and then it will just start dropping them off with "no buffer space available errors" I have this occurring on two boxes at the current moment. One is a dialup and the other is connected to a T1.
I will refer to the home box in this article. It is a p200 with 64 meg of ram and an 800 meg hdd. It is running FBSD 3.4 - RELEASE
root@cookies:/usr/home/trey# netstat -m
150/288 mbufs in use:
135 mbufs allocated to data
15 mbufs allocated to packet headers
32/46/8192 mbuf clusters in use (current/peak/max)
128 Kbytes allocated to network (64% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
root@cookies:/usr/home/trey#
I increased the mbufclusters in the kernel
options NMBCLUSTERS=8192
I also increased the maxusers to 128
one computer runs DLINK nic and the other has an SMC nic
Any suggestions would be MUCH appreciated.
