Hi all,
The below command crashes the io-net
ping -l 1500 10.0.1.1
while the same doesnot happen on my linux box. I am using a orinoco card
and in my rc.local i have

devp-pccard
io-net -dorinoco -ptcpip stacksize=8192 -pqnet
ifconfig en0 10.0.4.2 netmask 255.0.0.0

I have played with the stacksize settings till 32KB but to no avial.

Any suggestion will be welcome

Also
ping -l 100 also does the same thing.

Thanks
Srikanth

I just tried this on an ARM based 6.2.0 machine with the orinoco driver
and all three tcp stacks (tiny, tcpip-v6 and tcpip-v4) and nothing
is crashing. Are you getting an io-net.core file in /var/dumps?

Why are you starting a second instance of io-net in your local startup
script? There should already be one copy of io-net running at that
point. I suggest you try using the mount command, like this:

$ mount -T io-net devn-orinoco.so
$ mount -T io-net -o if=en0:10.0.4.2 npm-tcpip.so

See this page for details:

Hi,
Yes I have a io-net.core file in my /var/dumps directory. I dont know how
to debug it. Could you tell me how to do it so that I can find out what the
problem is.

Thanks

type gdb io-net /var/dumps/io-net.core.And then continue as if you are
debugging a live process.

coreinfo gives me the following output. I think thread 5 gets a egfault,
although I dont know why since I am just pinging.

Did you try using gdb to analyze the core? What did it say?

Hi Srikanth,

I had this problem also - I have updated to 6.2 patch A and the problem
appears to have cleared up…

I hope this helps

I have played with the stacksize settings till 32KB but to no avial.

Any suggestion will be welcome

Also
ping -l 100 also does the same thing.
