How did you install? Can you attach the plugin.ini file?

With broken Packstack (see the referred clone of this bug), but you can simulate it without the packstack, with the RPMs for sure. Obviously, the bug won't appear with Devstack because Devstack IMHO doesn't use the init scripts.

I don't have that config, but you should be able to reproduce it:

[root@master-02 ~]# echo 'I am evil as hell.' >> /etc/quantum/plugin.ini 
[root@master-02 ~]# tail -fn0 /var/log/quantum/linuxbridge-agent.log &
[2] 16976
[root@master-02 ~]# /etc/init.d/quantum-linuxbridge-agent restart
Stopping quantum-linuxbridge-agent:                        [  OK  ]
Starting quantum-linuxbridge-agent:                        [  OK  ]
[root@master-02 ~]# /etc/init.d/quantum-linuxbridge-agent status
quantum-linuxbridge-agent dead but pid file exists
[root@master-02 ~]# kill %
[root@master-02 ~]# 

See? No message. Only death.
