more on to previous reply (sorry hit the send button by accident)

For nova workers option:
osapi_compute_workers=None

And what is for keystone what option need to be set?
# The number of worker processes to serve the public WSGI
# application. Defaults to number of CPUs (minimum of 2).
# (integer value)
#public_workers=<None>

# The number of worker processes to serve the admin WSGI
# application. Defaults to number of CPUs (minimum of 2).
# (integer value)
#admin_workers=<None>


I'll try your solution and let you know the result.

Thanks,
Nader.
