[j-nsp] Media issue or some bug

[Truman Boyes]

Junaid,

I am assuming that you save HDLC on the E3s and that keepalives are  
on. Basically the IFD (interface) went into a "down state" and the  
sequence numbers between the peers differed....

Based on the logs you provided, it was likely a physical issue on the  
E3.

Kind regards,
Truman
