P1 smart meter LAN

[JoHi]

My p1 smart meter is connected with an EZL70A to my rpi 3. After a restart i find this log entry:

2016-07-30 14:15:47.405 P1 Smart Meter: connected to: 192.168.0.60:1470
It looks like the smart meter is connected successful.

After a wile the following error is coming up.
2016-07-30 14:17:00.239 Error: Smart meter hardware (8) thread seems to have ended unexpectedly

Is there any body ho can tell me what is going wrong.
