uwsgi emperor mod not working

Question

when i start it without emperor it works:

uwsgi --ini /etc/uwsgi/vassals/uwsgi.conf --uid books --gid books

But when i use emperor mode it freezes:

uwsgi --emperor /etc/uwsgi/vassals  --uid books --gid books

And give such response:

Thanks for your help.

UPDATE. Ignore my advice regarding master . Doc says that emperor mode should not be used with master normally. http://uwsgi-docs.readthedocs.org/en/latest/Emperor.html#notes

Try to run emperor with master process. Add master = true to your ini file and run uwsgi as root. Workers will downgrade to non-priviledged user (if specified)
