I think Lamar is right.
When I was using nsvhr, I would start my aolservers one at a time, in serial order, and I am almost positive the master was first.
I am not sure what those error messages indicate w/o looking at the code. It says address already in use. Does that really mean the unix domain socket doesn't exist just yet? Could be, or it might be something different.
I would recommend you try starting them up serially.
