[Impact]
Userspace daemon dies and all flows are lost during instance teardown on OpenStack hypervisor nodes; result is that all instances lose network access on the impacted server.
[Test Case]
Deploy openstack (sounds easy right); use it regularly and at some point instance termination will result in the userspace daemon dieing.
[Regression potential]
Limited; the fix is included in a new upstream point release which is covered by the usual upstream testing.
[Original Bug Report]
this crash has been observed a few times on this particular openstack cloud; result in loss of network connectivity to instances running on the hypervisor.
