[c-nsp] SUP2 on 6509 Crashing with BGP

[Stephen J. Wilcox]

Hi Richard,
 it'll be related to the IOS you are using and the features you have enabled.

You should be seeing significant memory being allocated for BGP, Routing, CEF

For comparison, I have a couple 7206s with 256Mb RAM doing some simple tasks..  
taking a reflected full feed (so hopefully minimal duplication of routing data)
they're down to about 15Mb free - time is running out!
