I have a product using the TM4C1294NCPDTI3 where it basically sends out a multicast packet when an I/O line changes. It works every time except in a situation where the I/O line doesn't change for about 2 days. When it does change after the extended time, the device crashes, then reboots after the watchdog expires. I'm not 100% sure it's the sendTo() call but it seems the most likely since sending the UDP packet is about the only thing the code does in response to the I/O line changing. I've looked through all of the socket options and don't see any that would intentionally configure this sort of timeout of the socket being functional. I also suspected one of my tasks was overflowing but all of my stack sizes are stable after an hour or so of run time. If anyone has an ideas I would appreciate hearing them. I'll continue to prove it's the sendTo() call that is causing the crash but it does take 2 days for each iteration.
Thanks
