Closing as it's unclear is this is still an issue. If you still see on
newer versions (i.e. Caracal) please re-open with more information.
Thanks.

Title:
  neutron-keepalived-state-change doesnt reap zombies if rootwrap-daemon
  is used

Status in neutron:
  Invalid

Bug description:
  I just tested the current stable/pike-branch of neutron.

  After some time our monitoring alerted us about increasing amount of
  zombie-processes. After taking a look, I found

  commit 91c26f56586e88a75e942cd06c8f4539acfb4963

  which seems to introduces some rootwrap-helper changes. I reverted the
  commit but the problem still remains, so maybe the commit is not the
  reason, but triggers the problem more likely.

  Steps to reproduce:

  * configure neutron-rootwrap-daemon
  * start l3-agents
  * wait for (ha-)routers to be setup
  * kill a rootwrap-daemon
  * sudo is now a zombie which is not reapd by neutron-keepalived-state-change.
