You need an "XL" size TCAM to hold more then 239k routes. You can adjust
the TCAM partitioning up to that from 223k with "mls cef maximum-routes
ip 239", but there isn't really much point in that now.

Otherwise you'd have to employ filtering on your BGP sessions, e.g.
discarding /24 prefixes or longer. You will then need a default route to
something that has full reachability, and you will have to accept less
than optimal routing in some cases.
