python - gunicorn booting unlimited workers -


i have flask application running behind gunicorn 0.17.2. after reinstall of dependencies (but no change in versions), gunicorn has started booting unlimited workers - or, more likely, starting, dying , being restarted (there no error reported however). cause of behaviour?
