I hit this as well - it's a bug in 11.1 and there is a PR open for it, but it hasn't been made public yet.
The fix is one of the following:
configure a static route on your box (doesn't have to be a legit route, but just needs to be installed the route table)
or use the following hidden command:
set routing-options max-interface-supported 0
According to JTAC this is a new command that has been added to limit the number of interfaces that participate in OSPF and PIM - the knob isn't meant for SRXs, but this bug seems to be affecting them.
