Hi.
I am seeing way too many errors on my dc0 external interface and I have
tried everything I can think of.
Running 4.0 on a p500+128mb ram as an internet gateway/donkey/torrent box.
# netstat -m

And I also see some queuing on the Send-Q when doing a netstat -an (max 64k)
sysctl mods are as follows:
net.inet.ip.forwarding=1 # 1=Permit forwarding (routing) of IPv4 packets
#random guesses for performance
kern.somaxconn=8192
net.inet.tcp.recvspace=65535
net.inet.udp.recvspace=65535
net.inet.tcp.sendspace=65535

kern.maxclusters=65535
kern.maxproc=4096
kern.maxfiles=8192
net.inet.ip.maxqueue=2048
net.bpf.bufsize=2097152
net.bpf.maxbufsize=4194304
load averages: 1.11, 1.24, 1.20

As mentioned above running rel 4.0 on a p500+128mb ram
as an internet gateway/donkey/torrent box with unmodified kernel
Googling on Ierrs tells me I'm running out of network kernel
bufs but certainly doesn't look that way from netstat -m.
Can anyone suggest what could be the problem? A 4.0 bug?
Additional sysctl line needed?
