Kiran, did you mean to dup this to 8801? 8801 has been resolved for a while so seems strange that this bug here is more recent.

Sam,
Fix for 8801 has been merged in master, but the cherrypick for stable/nitrogen is still pending merge.
Hence, this NETVIRT-907 was raised recently for nitrogen (I think RC2 was used to test this), since the fix is yet to be merged in this branch.
