Well, there is no magic there.
You should be able to first determine if your Ethernet frames are
arriving to your device and then being delivered to lwIP. Then you can check
What exactly are you doing with your PCBs ? You know a TCP connection
stays open for some time after you close it, do you ? If you happen to
open and close all of them, you'll have some time with no one left.
Does it recover after some time ?
Do pings get answered back ?
Are connections rejected ? Is your error callback called ? (Sorry, I'm
guessing you are using the RAW API; I already guessed you are using an OS)
Are you properly freeing pbufs ? (Sorry, guessing again)
