Cleaning this after a while, no further action is needed.
- T/X have a workaround in Neutron
- Latter versions of keepalive use systemd MAINPID tracking which is somewhat more robust in this regard

That said in the context this appeared it is fixed, lets set the old
tasks to Won't Fix unless there is a real need.

** Changed in: keepalived (Ubuntu Xenial)
       Status: Incomplete => Won't Fix

** Changed in: keepalived (Ubuntu Trusty)
       Status: Incomplete => Won't Fix

  keepalived fails to start when PID file is empty

Status in keepalived source package in Trusty:

Status in keepalived source package in Xenial:

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.
