> Hi team,
> I'm running qpid java broker with modelVersion8.0. And the client is qpid-proton with python. Unfortunately, my producer will randomly hit this "unknown QBB implementation" error thus failing with on_connection_error. Could you please help to advice what could be the root cause? The error call stack could be found from attachment.
> I'm suspending some null buffer is provided for this QpidByteBufferFactory.concatenate method. But I have no idea why it could happen. Would you please help to figure out? Thank you so much!
> Regards,
> Lisa
