Comment 1 for bug 2000783

After upgrade to yoga bug still is affecting.

The above workaround is not working for a newly created vpn endpoints.

So I found the new workaround: after restart neutron_l3_agent run commands:
docker exec -t -u root neutron_l3_agent rm -f /run/pluto/pluto.ctl
docker exec -t -u root neutron_l3_agent rm -f /run/pluto/pluto.pid
docker exec -t -u root neutron_l3_agent /usr/libexec/ipsec/_plutorun
