Hi Zeeshan,

Thanks for the hint.

OPA works fine, but then I found someone brought up a misconfigured node which 
has
the conflict IP address on OPA interface. Fixing it and problem solved.

This is a new node we brought online recently. Is it an indication that we have 
problem with
it OPA interface on the node? This machine has a 8160F CPU (OPA interface on 
chip).
