Are you seeing problems?  I'm loading 1.8 million paths in exactly such 
a router, with plenty headroom.  Some IOS versions leak memory like a 
sieve (and some leak only a little), though.  This is 12.2(28)SB10, an 
example of the latter; SB6 was an example of the former.  12.2(14)S3 ran 
literally for years and years on this particular router.

When the router starts complaining about lack of memory.  Personally my 
biggest worry with the above router is convergence time after more than 
a few BGP peers flap (which has actually gotten much better with SB over S).
