FRC2014 problem deploying with UDP write

Our students are trying to use an AndyMark AM-2645 (link) LED lighting kit. They've programmed the Arduino to accept commands over UDP.

Normally we have no problems with the robot. As soon as we add "UDP Write" to the robot project, build succeeds but deploy fails with an error that the cRIO closed the socket. It's during deploy; their code never actually runs. We've isolated it to adding this one VI. I didn't get a screenshot today, but will soon.

Couple questions:

1. Can anybody else reproduce this error? Is it a bug in the 2014 software?
2. Our interpretation is that R58 (link) restricts the dashboard to certain ports and types of communication -- we must use the cRIO to talk to the lighting controller, and cannot workaround by moving this feature to the dashboard. Are we right?
