Not that the FMS can't be temperamental, but as has been said, it's almost always the robot. I spent 3 weekends staring at the FMS console this year and in that time:
I saw well over 100 cRIO reboots.
I saw at least 3 dozen main breakers blow.
I saw a couple dozen situations where the radio or cRIO came unplugged during a match.
I saw plenty of drivers stations freeze.
I saw drivers unplug their joysticks or the drivers station Ethernet connection mid-match.
I saw a couple of robots running dual 1080p cameras kicking up around 15 megabits of bandwidth.
The closest I saw to an actual FMS (communications) issue was that the trip time from driver's station to robot spiked across all 6 stations to 120 milliseconds for a second or two then dropped back under 5 milliseconds. (despite my own concern, no robots dropped and the teams didn't notice anything during the match) Not to say that the FMS can't be an issue, but there are a lot of other places to look first.
