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.
