Team:

The issue that you have recently been faced with is a known one, and a
patch would have to be applied to fix this. I will have to consult our
OpenStack experts, and I will come back to you with a preliminary
resolution (if we can apply a fix and whether such ticket has already been
filed, etc.).

Kind Regards,
Dmitry.
