Public bug reported:

we are using openstack-neutron rocky with openvswitch versioned 2.10.0

We are using ubuntu 18.04 which shipped with a libc6 bug, reported here
https://github.com/openvswitch/ovs-issues/issues/175.

My question is that when this bug happens ovs agent will not working and reported dead observed from log,
but it still reports hearthbeat to neutron-server which is problematic because users will be unaware that ovs-agent is working anymore but looking at agent service state.
