Mike, I just did this with a ASR1001. I had to upgrade it to 8gb of ram (I got the real Cisco stuff for ~ $500). Before the router would crash when loading the tables.

But if I'm reading the above right, it looks like bgp is eating ~300mb on your box.
BGP using 296835018 total bytes of memory You would seem to have plenty of free ram. In my case, the ASR1002 doesn't have upgradable memory anyways so I'm stuck. Mike-
