The XMR and MLXe are limited to 786432 IPv4 routes and 65536 for IPv6
(ipv4-ipv6-2 profile)
If you want more routes you need -X2 linecards.
The IPv4 table and IPv6 tables are close to limit from the XMR/MLXe -x cards
(+-757166 ipv4 and +-65239 ipv6)
That is why you get the cam profile warnings.

To other platforms?
We still have a few of these running, and we appear to be about to hit the
wall.
What's going on here?

Router has been rebooted since those system-max limits were changed.

If I'm interpreting that output correctly, the router has a total of
917504 CAM entries for routes, it's split between v4/v6, and in spite of
the system-max settings, this router will be out of FIB space at 786432 v4
routes / 65536 v6 routes...or any moment now for v6. This router is
logging CAM partition warnings about free slots being low.
We're seeing the same on MLXe and NetIron chassis in XMR mode
running 5.6.0j.
