Basically this message just means that the master RE saw the backup RE 
disconnecting. TNP is the protocol used for communication between Juniper 
PFE components, you can find out what the specific component is by looking 
at the /etc/tnp.hosts file from the shell. For example:

> grep tnp:5 /etc/tnp.hosts
tnp:5           re1

As for figuring out WHY, the backup RE itself will probably have a better 
idea of what happened to cause the drop. It could be any number of things 
really, not just a version mismatch in the inter-RE communication API, so 
login to the backup RE and look at the logs there.
