We converted our entire 12K backbone to IOS XR, it was painful but
Its been relatively stable since. Haven't seen any issues like this. 
What SPA are you using?

Subject: Cisco 12000 series routers and IOS XR.

Is anyone on the list running the Cisco 12000 Series routers with XR? We
have a couple of these in our network and are having a few issues with them.

Specifically the line cards will reboot for some unknown reason
(12000-SIP-501). We recently replaced one of the cards and the new hardware
(<6mo old) is doing the same thing.

Anyone have issues with these routers?
