That should have been 32GB memory — the recommended 2GB per core!

Making progress :)
The main issues seems to have been that I was using pcap. Things behave sensibly when I use either af_packet or pfring.
I had to raise the flow.memcap to avoid the "Flow emergency mode over, back to normal… " messages.
I am sure that I will need to do more tuning before this goes into production but it will do for the moment.
Thanks for the pointers.
