Hi again Neale (and list)

I thought people would be interested to know we have found a possible solution 
to this - I was flooded with others saying they had similar problems.

It does boil down to some limitation with the Max - not doubt there. Whether 
its a CPU or actual interface issue I dont know.

ICMP requests on our network were 'flooding' the interface of the MAX - its 
only an 1800 so our 4060 or other people's 4060's may not suffer - who knows.

We killed all the default routes on all our servers and ran routed (routing 
daemon for Unix). We turned on V2 RIP send only on the max.

Our ping times over the ethernet dropped from between 5.5ms - 7000ms down to 
2.4ms to 500ms. Still not perfect, but we havent changed over all servers yet.

Regards

adam
