Unable to restart scheduler and broker on ubuntu 16.04

[fpeyre]

I install Alignak with the package for ubuntu 16.04
(At the moment when I make this issue : alignak-all_0.2-1.1489300848.c527ae7_all.deb )

I have some issues when i want restart with systemctl the scheduler and the broker

For the scheduler, after systemctl restart alignak-scheduler, I make

systemctl status alignak-scheduler

I make the same thing for the broker. We have a different error message

systemctl status alignak-broker

I don't know if it's specific to the package or alignak itself. If I am at the wrong place, i will create the issue on Alignak.

I am available to make more test or give you more information

Ok for more information:

My use case is not just a simple restart.
I make systemctl start alignak-scheduler once
I make a restart, everything seems work
I make systemctl start alignak-scheduler
I make restart -> We have the error message

I join the log in a file
schedulerd.log.txt
brokerd.log.txt

In the scheduler log, the interesting error is:

This problem happens once the scheduler got started and received a configuration. All the previous start/stop of the daemon do not raise any problem.

Note that the broker has the same behaviour 😉

And I think that this may be related with Alignak-monitoring/alignak#673
