Running HSRP, but doesn't make a difference which of the two routers is 
active. The second router is currently active for all interfaces and groups.

Yes, running PIM-SM. This box is DR on some subinterfaces and not on a 
few others, but changing DR priority doesn't seem to make a difference.

I don't see how it could be related to any traffic coming into the 
interfaces, because the interfaces are programmed to handle certain 
features in software even when they are not receiving any traffic.
