Thanks for the clarification.
What is the highest safe value I should raise NMBCLUSTERS to on x86? How
many states max will it keep?
I don't think NMBCLUSTERS has much to do with the number of states
you can keep on a system. States are not allocated from clusters memory.
NMBCLUSTERS is used by IP packets that are in transit in your box,
(or packet in IP/TCP reassembly queues). While you need a decent value
for it if you've a lot of traffic, increasing NMBCLUSTERS will not change
the maximum number of states you can use. NKMEMPAGES would be
a better knob to tweak, but if you increase it past 64M (don't know what
the default value is), you will start to have instability on your box.
