What does your /etc/dat.conf look like? What is the listening port on 
each interface and what address/port are  you using for each connection?

Also, can you run ucmatose to verify rdma_cma is working correctly 
across each interface?

For example:

start a server on both interfaces (I am assuming 172.200.0.1 and 
172.200.0.2)

ucmatose -b 172.200.0.1
ucmatose -b 172.200.0.2

start a client on each interface on the other system

ucmatose -s 172.200.0.1
ucmatose -s 172.200.0.2

Thanks,
