Just an FYI that the default value for rpc_workers has changed, if you 
look at the Stein or later config it's now:

api_workers
     Type
         integer
     Default
         <None>
     Number of separate API worker processes for service. If not 
specified, the default is equal to the number of CPUs available for best 
performance, capped by potential RAM usage.

rpc_workers
     Type
         integer
     Default
         <None>
     Number of RPC worker processes for service. If not specified, the 
default is equal to half the number of API workers.

There is a doc in the neutron repo available via docs.o.o:

https://docs.openstack.org/neutron/train/admin/config-wsgi.html

The last section of that covers "Neutron Worker Processes", and might be 
helpful.  If you think it would be useful to add a little more info on 
this failure please either create a patch (file is at 
doc/source/admin/config-wsgi.rst in the repo), or open a bug - sometimes 
these low-hanging fruit things are great for someone new to the project.
