[j-nsp] Media issue or some bug

[Junaid]

Hi,

Three of my E3s (on two different PICs) from my core M320 towards my
remote M7 went down all of sudden (at the same time) and stayed down.
I am receiving similar logs on all the routers:

After a few hours, they came back online - and we did not change any
configuration on any of the routers. Can anyone give me a clue as to
what caused this error message to surface?
