Except that some times, it did lead to crash (for us 
anyway), because it eats up half the router's memory, and if 
you're running 3x full tables or more, you ran out of the 
other half and BOOM! And that was IOS XR 2, which is 
generally old now.

We now turn off software redundancy now on all ASR1000 boxes 
that don't have a 2nd RP.
