In our experience the problem starts with bus signals not activating. e.g. a light switch that was working ok suddenly starts to play up intermittently. The problem worsens over time.
One sure way to tell - Switch ALL of the lights off and try to repeat the error!
The installations where we have diagnosed this fault you could start with all the lights off and switch individual light circuits on and off OK when you got to about a dozen light circuits on the problem started to occur and worsened the more circuits were on, eventually it would simply lock up.
