Hm, I'm not totally convinced that you have pf_ring fully working yet.  My guess is that each of those workers saw the same packet.  Connection unique IDs will be generated differently on different hosts so you can't expect those to be the same and everything else, including the timestamp is exactly the same. 

Can you send the output of:

broctl config | grep -i pfring

and:

ldd <prefix>/bin/bro

If there is a problem with pf_ring not being enabled correctly on some machines, we'd certainly like to figure it out.

Thanks!
