Eugene (& list) I just saw that you reassigned the bug to yourself recently , and that the ideas described in the bug differ a bit from the idea that I had, but I'd be willing to extend my spec to incorporate your design and spend some time in the problem if you believe it's feasible. I'm talking about: https://bugs.launchpad.net/neutron/+bug/1257524 and https://review.openstack.org/105999 http://docs-draft.openstack.org/99/105999/1/check/gate-neutron-specs-docs/86e0554/doc/build/html/specs/juno/agent-child-processes-status.html Best regards, Miguel Ángel.
