You can try restarting the PFE process. I had to restart/kill the PFE process when I was configuring Filter Based Forwarding to send traffic to a new instance. The PFE wouldn't install routes into the new instance, even with a config force. This was 2 EX4200 in a VC under JUNOS 11.4R2.14.
It can help reduce downtime if you can have HA features enabled. root@switch> start shell root@switch:RE:0% ps -aux | grep pfe root 1284 1.0 2.3 86804 23388 ??
