Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Yakkety has 1.2.20, so this is Fix Released. You asked for a backport
but you haven't said what package version you're using, what release you
want the fix backported to or in which releases you have confirmed the
bug to exist. Is it Trusty, Xenial, both or other? For each one, please
can you state whether you have confirmed the bug to exist?

** Changed in: keepalived (Ubuntu)
       Status: New => Fix Released

Title:
  keepalived fails to start when PID file is empty

Status in neutron:
  New
Status in keepalived package in Ubuntu:
  Fix Released

Bug description:
  After a crash of a network node, we were left with empty PID files for
  some keepalived processes:

   root@network-node14:~# ls -l /var/lib/neutron/ha_confs/0ab5f647-1e04-4345-ae9b-ee66c6f08882.pid
  -rw-r--r-- 1 root root 0 May 19 08:41 /var/lib/neutron/ha_confs/0ab5f647-1e04-4345-ae9b-ee66c6f08882.pid

  This causes the L3 agent to log the following errors repeating every
  minute:

  and the keepalived process fails to start. As a result, the routers
  hosted by this agent are non-functional.
