[j-nsp] cfeb errors

[kwarteng at myzipnet.com]

Hi,

My Juniper M10 router interfaces suddenly became unreachable. After getting
someone to the remote site and rebooting it, the interfaces were reachable
again. A close look at the logs points to issues with the cfeb just before
the loss. Am I losing my cfeb or I should be looking at the chassis? Do I
have to be looking at changing the router altogether?
