Comment 2 for bug 1612192

I took another look through logstash and found this message had mainly happened in these check jobs in the past 7 days:

gate-tempest-dsvm-networking-sfc-nv
gate-grenade-dsvm-networking-ovn-nv

Those are both non-voting.

There were a few in the gate-tempest-dsvm-neutron-dvr-multinode-full job, but in the noise, so I'm not sure this is critcal, unless my searching is wrong.
