Can it be some problems in PPOS input path? Some data that may hang PPOS in case of bad input. I doubt this is stack overflow or timer wrap-around, I have double checked this -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html ___ lwip-user

I know it's a long shot, but I'm gonna go off on a tangent and ask how your system does elapsed timing? Bottom line: check that your timers aren't rolling over.  If you happen to have a 100 kHz clock and use it to time things with 32 bit unsigned integers, it'll roll over in about 12 hours (we
