[c-nsp] Odd problem with bgp resets on SRD3

[Mack McBride]

I am looking at 2 - 7600s with RSP720-3CXLs w/ 4GB of RAM and 6708-3CXL cards running SRD3.
These are not currently production equipment but are connected to upstreams
as well as route-reflectors but are not advertising routes as we have advertisements blocked
with a deny-all prefix list.  We THINK the dumped BGP packet is correctly formatted and
the packet dumped is actually the packet before the bad packet.  Has anyone else
seen similar issues?  Does anyone else know if this is a known bug that exists in this code or
early versions of the SRD train?  I know there are entirely too many caveats in SRC5.
