I'm marking bug a confirmed for now. Sergey Kraynev (Heat team) is going to check if upstream fix (that was merged to stable/liberty and stable/mitaka) is included to MOS 9.0 and MOS 8.0.

[Oleksii Chuprykov (ochuprykov)]

Waiting for a merge-sync.

[Peter Razumovsky (prazumovsky)]

Fix also merged in 8.0 branch
