We saw as similar message in our CRS1 routers in IOS-XR 3.9.2.  It was
attributed to CSCrf80648, which confirms the limitation for BGP
attributes at 65k entries.  The limit is increased in IOS-XR 4.0.0 for
the CRS1 to 256k entries.

Possibly oli can confirm if there is a similar enhancement for the 12k.

If there is not an enhancement, it is a hard limit and you are limited
in the options - either ignore and have some missing attributes, or
disable attribute download entirely.

If you choose to ignore, you may want to check out Logging Suppression
Rules - these are for the CRS, but I assume the command syntax is the
same on 12k.
