[Rodolfo Alonso <1921866@xxxxxxxxxxxxxxxxxx>]

This is the same problem as in [1]: the keepalived-state-change process
do not finish the "handle_initial_state" execution, stopping any further
processing. At this point, the process can be considered as zombie.

>From the journal logs [2], from [3], we can see how the process is
started and never reaches [4].

I'll mark this LP bug as a duplicated of LP#1917793.

Regards.
