this is definitely this bug. Disabling solves the problem

Perhaps it's CSCtd26215. If BGP dampening is enabled, give a try disabling
it.

Hello all,
We have faced the same problem when we have tried to update to version
SRD4.
Our hardware is Cisco 7600 with RSP720-3CXL-GE with 2GB RAM and
WS-X6704-10GE.
We have observed the bgp notification in logging such as "neighbor
1xx.x.x.x 3/1 (update malformed)".
The all sessions get down after that with message "Down No memory"
Who was faced with such problem also? How to solve it?
We had the following errors log occur:
%BGP-5-ADJCHANGE: neighbor 1xx.x.x.x Down BGP Notification sent
%BGP-3-NOTIFICATION: sent to neighbor 1xx.x.x.x 3/1 (update malformed) 0

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.
