[j-nsp] vlan-ccc subinterface down

I have 2 EX4500 connected via an mpls/ldp backbone. I'm running l2circuits
between the two boxes to haul vlans.

I have two vlans working between the endpoints on the same physical
interfaces.

I need to add a third vlan but I'm getting a vlan-ccc down error on the
subinterface on one of the ends.

Is there a limit to how many vlan-ccc can be on a physical interface on an
EX4500?
