Hi Fabian,
We are running Pike. We have DVR with centralized SNAT on L3-HA routers. We also have L2 population enabled which I think is responsible for the issue. We can reproduce the issue almost every time we are spawning 100 VMs at once. Usually 3-6 VMs have no connectivity to services running on network nodes like DHCP, DNS so they don't have network configured. As I mentioned in the bug we also observing issues with L3-HA routers provisioned using Heat. After debugging I'm almost sure there is a race condition which is triggered by massive network resources provisioning. When we provision routers manually we always have a working router.
