It seems to be stopping before getting to creating a new Minion instance. I'm confirming with our java developer but I believe it binds to localhost so Minion can tell if another instance of Minion is running. So if there is something weird in your hosts file it might mess Minion up? It's been so long since I've come across this issue I'm waiting to hear back from our java developer to make sure it still works like this.
Does your /etc/hosts file have the following line?
