Dear David, I'm in the exact same case. I have started seeing those exact IPv6 CAM error related messages 3 weeks ago. Interestingly enough, only getting those for MLXe boxes and not CER-RT.
I'm running 5.7e and about to upgrade to 5.8e. If memory serves right, I think I read something in some release notes (or other documentation) about a special feature/profil that would accomodate CAM for 1 VRF. I can't seem to recall which, so I'd invite you to read the litterature. Also, IIRC, I think I read That someone put up an RFE for this following your thread two years ago.
