Reset problem with ethernet gateway and a sensor

[hyla]

Hi,

posted that on Domoticz, too...

Strange thing here: I've got a MySensors sensor here (some variety of a temperature-humidity sensor).
Gateway I'm using is the ethernet version. Whenever I reset my sensor the ethernet gateway resets too:

2016-02-27 10:14:12.664 MySensors: Connection reset!
2016-02-27 10:14:12.665 TCP: Reconnecting in 30 seconds...

2016-02-27 10:14:44.672 MySensors: Gateway Version: 1.5.1

Each and every time.

In the WireShark protocol this is reported:

So the gateway seems to answer once (29) and then it resets.

So far this type of sensor is the only one who does this.
I do have another practically identical sensor who has the same effect. Both have worked before.
Although I might have changed something in between. Other sensors work flawlessly...
Electrically sensor and gateway are completely separated (sensor driven on a battery, gateway feeds on a 2A wall wart).
The sensor is not detected (anymore).

This is what I get from the serial port when connecting to that:

send: 8-8-0-0 s=255,c=0,t=17,pt=0,l=3,sg=0,st=ok:1.5
send: 8-8-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
read: 0-0-8 s=255,c=3,t=6,pt=0,l=1,sg=0:M
sensor started, id=8, parent=0, distance=1
send: 8-8-0-0 s=255,c=3,t=11,pt=0,l=8,sg=0,st=ok:Humidity

send: 8-8-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,st=ok:22.2
T: 22.20
send: 8-8-0-0 s=0,c=1,t=1,pt=7,l=5,sg=0,st=ok:41.8
H: 41.80

Any ideas?

Thanks,
