ASR 1000 does not run XR. You probably mean XE. 

The high availability features that requires maintaining state and stateful switch over never seem to work out of the 
box on early releases and need some time until the feature gets mature. I've found this across different vendors.

The dual IOS process works best with two Routing Engines/ESPs on higher models.  contact your local vendor engineering 
representatives asking them for more details on the the ASR1K High Availability features and they should tell you how 
it works in detail.

The warm standby IOS is a nice
feature for in service upgrades and crash avoidance.

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.
