Often happening ModbusTransportException #41

I can successfully get the data, but meanwhile I am getting many of ModbusTransportException: Unsupported IP protocol id. Have no idea what to do with it.

Checked the dump from Wireshark. The device answers properly in short time (about 0.5ms). Seems MessageControl or InputStreamListener screwed up in some way.
