we ran wsgi compliant web server which calls Stream UDF lua function. Everything was working well with gevent.wsgi, but recently we are moving to Gunicorn Wsgi. Unfornutelly with this setup Stream UDF call get stuck. Function doesn’t return any value and blockes forever.
query = self.client.query(self.COUNTERS_NAMESPACE, self.COUNTERS_SET)
query.apply(self.FREQUENCY_MODULE, self.FREQUENCY_REACHED_FUNCTION, [ts_now])
records = query.results()
Stucks on the last line.
Any thoughts on this?
