Description (partial)

IPFIB on final image should continue to run as expected masking the problem which may have a minor or no impact.

When ECMP path table is scaled, IPFIB crashes during a prefix update when next hop is changed to a vobj. This is not seen in final image.

When ECMP is scaled to 85% or more, there is a chance a traffic loss may be seen (no crash in final image) when there is a prefix update for which the next obj is changed to a new vobj due to change in RNHs.  This is minor because the old next hop vobj object was already removed from the hardware. IPFIB crashes only in gdb build. Final image should continue to work without problems since the new next hop object will be linked.
