My take on the situation is that both programs work alone on the Due.
Thus it is not a Due problem but a software problem, programming forum.
The Servo2 example will not compile with genuino 101 either.
I will not be writeing C code for anything.
All 6 interupt timers are not being used by the servo.
Interupts not being used by program A should be available for use by program B.
The servo grabbing all of the interupts is not isolated to a Copperhill conflict.
I will not post his code as it is his not mine.
He does refer to Timer Interrupts on Due - Arduino Due - Arduino Forum.
Tip: Anyone thinking of useing CAN bus this is the place to go.
