Ethernet Gateway/Domoticz Connection Reset

[martrw]

I have the following setup:

Domoticz controller
Ethernet gateway/W5100/NRF24L01+
Prototyped Relay Controller

All hardware(Arduino, W5100, NRF24L01+) is powered from a power bus with stepdown regulators for the radio. The power supply is a converted AT 300W supply so I would say the power is clean and current is not constrained. The MySensors code is 1.6 and not altered in any way.

According to the Domoticz log, the TCP connection to the gateway is reset after connecting for only about 500 msec. Domoticz then "says" it will re-establish the connection in 30 seconds, although this timeline does not seem to be supported by the log. The physical 30 second delay occurs between these two lines:

2016-05-28 09:07:24.715 MySensors: Gateway Version: 1.5.4
2016-05-28 09:07:52.423 TCP: Reconnecting...

After re-establishing the connection it will be reset again in ~500 msec. This repeats ad infinitum

Domoticz log:

The led representing the relay continues to operate (affirmed visually) from Domoticz throughout this trauma as indicated by this log section:

This is strange since the log indicates that there is no TCP connection!

Based on recent experiences with this forum and the below referenced similar issues I am not banking on a helpful response here but I thought I would try before tossing all this hardware in the trash.

1. Is the TCP connection actually reset or is the code reporting non-issues?

2. Which code, Domoticz or MySensors, would report Connection Reset when there seems to be an established connection?

Looks strange.
What does the debug say for GW?

[johnecy]

I am having the same problem with Domoticz. I know the gateway is working because I have it connected to Vera Lite as well and have no problems with it. Been trying to figure it out but at a dead end.

[martrw]

I restarted Domoticz for a non-related reason and the issue ceased. I have tried to create the sequence of events that led to the problem the first time but at present Domoticz logs are quite and things are working as they should.

[sundberg84]

In newer Domoticz versions it tries to ping the gw. If something is blocking this (like another controller) it will reset and try to connect again. This happened to me when i connected two controllers (Domoticz + Myscontroller) to the same ethernet gw...
