Hi Darren, Do you see any high usage of CPU or RAM? How many prefixes do you receive? Can you please provide the config? Do you see any stuff going on f.e. via tcpdump? Filter on port 179? Is there any conspicuous bump in f.e. bgp updates going on? Filter on bgp.type or try to graph it.
Overall you could try latest code from website, but I don't think that you are hitting a bug, at least at the moment ;-) Rgds, Stefan
