No it stops completely. The receive window is open. However I am not sure
about the congestion window (might be messed up). Or it could be a bug in
my application :-(

Does it stall for a few seconds and then resume? I was seeing this on my
system, and the stall was occurring on the host computer. The reason was
that the TCP window on my lwIP board was small enough that Window's Nagle
algorithm was kicking in. Might not apply to your system, but is just a
thought.

Subject: [lwip-users] lwIP TCP connection stalls?

 

Hi,

 

I am having a problem where the TCP connection between a linux client and
lwIP's TCP stalls randomly i.e. the traffic flow between the two endpoints
stops completely. I came across the following thread in the mailing list
with similar symptoms;

 

http://lists.gnu.org/archive/html/lwip-users/2006-10/msg00114.html

 

However I didn't see a resolution for it. Does anybody know the
resolution?

 

PS: My application is a transparent TCP proxy using only the TCP layer
from lwIP. I am analyzing the pcap dumps using tcptrace/xplot. If people
would like to take a look at the traces for themselves let me know and I
will post the pcaps. I am sure people like tracing tcp flows :-)

 

Regards

Ram
