[c-nsp] If BGP is running on a circuit, if you ping the other end you get loss. kill the BGP (and thus the traffic..) no more loss.

Can you post show version and the show diag (looking for engine and memory
only) of the affected cards. Also what is the current utilization of the
circuits that you are seeing issues on?
