Yea its a bit strange that we would need to add memory to the platform just because we upgraded the image. 
But since we were in kind of a tight spot we opted to upgrade it and then move away from the platform in that role.

Hi Gustav,

IMO, you should not accept that answer from the TAC. An IOS release that crashes with two 600k BGP feeds in 4 gigs of RAM is badly defective.
