Hallo Sergio,
I know that there is no such thing like IP connection, sorry for the
incorrect phrasing.
I'm using the sockets API. The OS is VDK (Analog Devices).
I can't post the traffic since it is the traffic of the customer. Everythig
works fine almost all of the time. It does only happen at one customer,
never in my lab.
The traffic of the customer showed a kind of ARP flooding (but not from our
devices). That was the only remarkable thing I could see in the traffic.
After that I could not ping our devices, Webserver(TCP) was not reachable,
SIP Message (UDP) did not go out any more.

I've got several tasks using different UDP and TCP sockets for SIP, MDNS,
NTP, HTTP Server etc.
I've no way to look at lwip_stats in a installed system, since I have no
access to it except ethernet.

Sandra, lwip is stable, you should check your product.
As you probably know, there is no such thing as an IP connection, so if you
are specific on what you are doing and what is the problem you are having,
there is a chance to find a solution or at least the culprit.
If you want to take traffic captures and post links to them, I'll be happy
to take a look.
If you want to log lwip messages and describe what your usage is (NO_SYS,
OS, API), sure someone will be happy to look at it and suggest.
