[dpdk-users] How to use multiple distributors

[Choxmi Sathsara]

Hi,

I am trying to use multiple distributors to fetch data from different
ports. I have assigned different lcores for distributors and starting
worker ID from zero for each distributor.

That's working fine up to some level. I can send upto 20G between four
machines. But, just after connecting the third set of machines, application
get crashed.

I have attached the backtrace for the error. It seems like it get crashed
from `distributor_process` method.

Please help me to find a way to achieve this.

Thanks and regards,
Choxmi
