CPU spike to 100% - robot unresponsive

The complete loss of connection you see about 75% of the way through is where our drivers did a remote soft reset of the cRIO - it comes back up just seconds before the match ends, I think.

So that log definitely has something wrong. The line that is across 16 shows what the DS is commanding to the robot. The lines above that show what mode the robot is actually in. By the looks of it, it looks like the robot stopped reporting what mode it was in when the cpu jumped to 100%. I don't know if its the FPGA that reports those things, or if its the CPU, and that would be a question that the NI people could answer better. But that could help get a better understanding of where the error is.
