There was an issue with the C++ NetworkTables implementation that only appeared when there were several robots all updating a number of variables very frequently. This usually occurred with SmartDashboard but would also fail with the default LabVIEW dashboard and NetworkTables or any other NetworkTables client program on the robot network.
There is a new version of WPILib that will be required for C++ teams that has been posted here:
