Description (partial)

FP reloads with the core file reporting:

This issue only applies to ASR1001-X, ASR1002-X, ESP100 and ESP200.  To hit this issue, three rare conditions internal to the QFP forwarding engine have to be present at the same time. These conditions are influenced by which features are configured, instantaneous traffic characteristics, as well as instantaneous processing load on the QFP. It is very, very rare for these conditions to occur.
