[c-nsp] Cisco GSR Chokes on BGP

[Billy Guthrie]

Dominic,

I have a link in my history, so I am sure that I have seen the issue but 
do not recall the specifics.

Good luck.

As soon as the BGP session comes up, however, the line card crashes/resets. Setting the maximum-prefix BGP parameter to a really low level makes no difference.  The LC is configured with the maximum possible MEM available for that device, and this is the only BGP session on the entire box.
