Different models of linecards need different amounts of RAM for the same 
amount of routes. For instance, the 4GE gives up earlier when having just 
256M of ram (we had to upgrade a year ago or so) compared to the 3GE 
(which still works).

You need to monitor your RP and LC memory as well as your "show ip cef 
resources". Make sure your RP and LCs have *at least* 50 megs of ram free 
at all times, it's sometimes needed during a re-route.
