[Bug 1629097] Re: ovsdb-client processes not getting cleaned up

[Corey Bryant]

This may be the issue, though I don't know the code well enough.
https://github.com/openvswitch/ovs/commit/fe5593818dca05b03804de5d99a9edd125f2d440

service_start without any corresponding service_stop

Title:
  ovsdb-client processes not getting cleaned up

Status in neutron:
  New

Bug description:
  This can be recreated with the openstack charms using xenial-newton-staging.  On newton deploys, neutron-gateway and nova-compute units will exhaust memory due to compounding ovsdb-client processes:
  sudo /usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf ovsdb-client monitor Interface name,ofport,external_ids --format=json

  $ top -n1 -b -o VIRT
  http://paste.ubuntu.com/23252407/

  $ ps aux|grep ovsdb-client
  http://paste.ubuntu.com/23252658/

  Restarting openvswitch cleans up the processes but they just start piling again up soon after:
  sudo systemctl restart openvswitch-switch
