Bug#786963: asterisk: running /etc/init.d/asterisk start after a crash, or after issuing a stop via asterisk console doesn't start asterisk

[Simone Ricci]

Package: asterisk
Version: 1:11.13.1~dfsg-2+b1
Severity: important

Dear Maintainer,

trying to start asterisk via /etc/init.d/asterisk start, or by issuing a systemctl start asterisk fails (nothing happens) if machine is recovering from a crash, asterisk itself has crashed or stopped via its console. That's probably related to systemd seeing it running even if it's not.

How to reproduce:
* Start asterisk normally
* Stop it via its console (eg. asterisk -rx 'core stop now')
* Try to start it again, either via /etc/init.d/asterisk start or systemctl start asterisk
* Nothing Happens and systemctl reports the software as active, for example:

	root at softswitch-02:~# systemctl status asterisk
	● asterisk.service - LSB: Asterisk PBX
	   Loaded: loaded (/etc/init.d/asterisk)
	   Active: active (exited) since Thu 2015-05-14 00:42:53 CEST; 1 weeks 6 days ago
	  Process: 521 ExecStart=/etc/init.d/asterisk start (code=exited, status=0/SUCCESS)

* Notably, when asterisk is effectively running, the output is a bit dissimilar (systemd shows relevant processes):

	root at softswitch-02:~# systemctl status asterisk
	● asterisk.service - LSB: Asterisk PBX
	   Loaded: loaded (/etc/init.d/asterisk)
	   Active: active (running) since Wed 2015-05-27 10:31:52 CEST; 17s ago
	  Process: 5759 ExecStop=/etc/init.d/asterisk stop (code=exited, status=0/SUCCESS)
	  Process: 5769 ExecStart=/etc/init.d/asterisk start (code=exited, status=0/SUCCESS)
	   CGroup: /system.slice/asterisk.service
		   ├─5775 /usr/sbin/asterisk -p -U asterisk
		   └─5776 astcanary /var/run/asterisk/alt.asterisk.canary.tweet.tweet.tweet 5775

BR,
Simone.
