Thanks for the pointer.  I found this posting from Robert:

so we might not get too lucky with having even two full feeds on a pair of ASR1001.

I will definetely want to do more research on this and open a case with our cisco contacts. We do not have redundant IOS processes as I was able to verify now and the box has 4 GB of ram so I would expect to see 2 GB for IOS on accounts of above posting but we are only seeing 1 GB usable ram.

Greetings
Christian
