Hi Brian Thank you for the fast reply. It is very appreciated.
I cannot check if it works without DVR on that particular cloud. I have other users there and I dont wanna touch the (sort-of) production setup. Nobody seems to use SCTP and DVR just works fine for usual TCP/UDP workloads. However I can try the Liberty release on top of some other nodes in my lab: 1. I will try Liberty (without neutron DVR) and see if it works there. 2. In case it does I will do the same thing with DVR and hope it still works. ;) I will have to wait until next week to check that. I ll keep u informed.

Can you verify it works without DVR and/or with the latest Liberty code? There have been a number of bugs fixed in the DVR space since Kilo, and perhaps something needs to be backported.
