If anyone can shed some light on this, I'd be really interested try an understand what's happening. I'm hoping that I can create a similar piece of code on my Linux box to generate packets and send them to the cRio to test to see if it has the same failure mode.

Does this occur only if you open a socket on that port and never read, or also if you never open the socket at all?

BTW, the DS to cRIO port is only for crossing the field network. You should use ports outside the FRC range (as defined in the rules) for on-robot traffic.
