[j-nsp] pfe_listener_disconnect errors on M120

[Ying Zhang]

we have a M120 with dual REs. I noticed error messages on the log file

On the Master RE:

I googled it, seems it happens when the two REs running different versions 
of software. But my two REs run the same version 8.4R2.4. Any sugguestions?

Thanks in advance.
