Public bug reported:

Hi All,

We have OSA Yoga setup. The neutron linux bridge agent is wildly
fluctuating, the agents going up and down in the `neutron agent list`
command.  The count of the agents which are down is very intermittent
and changing every few seconds as shown below:

----
38
root@utility-container-:~# neutron agent-list | grep Linux | grep xxx | wc -l
neutron CLI is deprecated and will be removed in the Z cycle. Use openstack CLI instead.
34
root@utility-container-:~# neutron agent-list | grep Linux | grep xxx | wc -l
neutron CLI is deprecated and will be removed in the Z cycle. Use openstack CLI instead.
43

82

As shown above, the agents down count is fluctuating within few seconds
gap of executing the above command. The logs on the network nodes are
not indicating anything wrong. Why is this happening ?
