As I said the 128.0.0.1 is an internal IP address. You don't configure that. Those addresses are used internally for the router components to communicate.
ylara@R1> show route 128/8 all
__juniper_private1__.inet.0: 7 destinations, 9 routes (7 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

I don't know about the log message. I would open a case with JTAC to find out.
