The OP is right, I have seen Juniper routers (both MX- and M-series) log error messages in certain scenarios, particularly if the stack was larger than 3 labels, if my memory is anything to go by. This was Junos 10.4R4.5. In my case, that log was on the back of an NG-MVPN deployment, and only participating routers logged the issue. That said, the log never resulted in any service issues. It appeared while were troubleshooting something else. Mark.
