Hi all,
Unrelated but for everybody unknown with mpd:
FYI:
DESCRIPTION
mpd is a user mode PPP daemon using the netgraph(4) networking system.
By using Netgraph, mpd combines the robustness and flexibility of a user-
mode PPP implementation with the speed and reliability of ker

somewhat unrelated, but..
After 4 hours of pinging and listening to a shoutcast stream natd rised to
his state of eating 34% proctime (top)
Connection timed out, did a restart of mpd and everything is running normal
agian.
Bugs me.
Grtz,

i too am currently looking into natd - it seems to eat more cpu as the

Sirs,
Thank you for the clarification about 'no buffer space available' .
First of all I want to bring a new flavor of a test I did.
Switched back using natd again, used ping -s 4096 www.bart.nl and off
course a 128k/bits winamp stream from digitally imported ;-) to see what

As i suspected, you have a quite small number of mbuf clusters
in the system. I am unsure on how much memory you have and how
your box is used, but mbufs are used quite a bit in the system.
Each fxp device allocates 64 clusters in the receive queue, and can have
up to 128 in the NIC transmit queu
Ok, I have refrained from jumping into this thread but
the noise is increasing and I think some clarifications are
really necessary now.
First of all: at various levels in the protocol stack, when
a packet cannot be forwarded to the next layer, more often
than not a ENOBUFS error is returned, wh

Well it could be mpd, but my good old friend ;-) tested a view things.
First he used DUMMYNET to simulate his ADSL connection in a LAN environment
(100baseT)
So he put in some packet loss and bandwidth limitations on his LAN and
started pinging some hosts. He gets the same result of packets be

Thanks for the quick reply.
But I want to come back first about the identical system a friend of my is
using only with the xl driver for his public interface.
But today he told me when pinging to a host like ping -s 4096 www.bart.nl

Yes. I was going to commit this fix to -stable at bsdcon, but the
number of problem laptops that I wanted to look at closely didn't
allow it.

Hi,
Thanks for your reply.
added sysctl,
Set the default value's of 4.3 in the kernel.
net.inet.tcp.sendspace=16384
net.inet.tcp.recvspace=16384
But still no buffer space messages when pinging a host.
Can I try something else?
also tried to lower udp.recvspace, but did not help :(
