If you run any TCAM based system and take full BGP tables on them, then, yes, you: A: should be worries and / or B: should have started trimming tables to fit in CAM and / or C: should have started fiddling with the CAM sizing / layout and / or D: be chatting with your vendor and checking the CAM size on your line cards. There is no evidence yet that it was CAM exhaustion vs any of a whole bunch of other failures, but hey, now at least you know to start looking :-P W
