@Robert Cotter Thank you for your reply 
I try the solution you given , but i didn't work.

Maybe it's the pf_ring that causes the problem.
When i used tcpdump, i finded the same problem of Dropped Packets.
Runtime environment:
NIC is Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe
pf_ring version is 7.1.0
bro 2.5.5
linux:centos

I would suggest doing some reading on Bro clustering going a little deeper
on your 'lb' configuration.
Not knowing what the data/packet rates you are attempting to process but
in my experience asking a single process thread to do more than 300 Mb is
going to ensure you get packet drops.
Below is part of my node.cfg for a 500Mb complex network data test lab
setup I am currently running hosted in Centos KVM so I can learn/test some
of the DNS/SSL scripting features.
[worker-1]
type=worker
host=localhost
#Interface=dag0
lb_procs=4
lb_method=interfaces
lb_interfaces=dag0,dag1,dag2,dag3
pin_cpus=4,5,6,7
Hope this helps you.
Regards
Robert Cotter

<CAHv=
Content-Type: text/plain; charset="utf-8"
event bro_init()
{
Log::disable_stream(HTTP::LOG);
}
But i want scripts using HTTP protocol to work e.g
https://raw.githubusercontent.com/sethhall/bro-scripts/master/top-websites.bro
Is there any other way to do it ?
