[rabbitmq-discuss] "service rabbitmq-server start" hangs when using python's Popen from subprocess.

[Raphaël De GIUSTI]

Well, I have the same problem when subprocessing
"/etc/init.d/rabbitmq-server start".

Note that I have no problem subprocessing "service rabbitmq-server status"
or "service rabbitmq-server stop" (or any other service).

My only issue is with the start method of /etc/init.d/rabbitmq-server init
script.
