No - it won't work without debug symbols to poke around in pythons
runtime. Can you share the log?

Do you see anything from:

                    self.logger.warning('Extra log data read: %s\n' % (data.decode('utf-8', errors='backslashreplace')))
                except Exception as e:
                    self.logger.warning('Extra log data exception %s' % repr(e))


maybe we should have a: self.stop_thread() once we catch the exception?
