[SOLVED] Wifi gateway crashing ~20min

[carlyler]

Re: WifiGateway crashes after 1 or 2 days

Similar issue: ESP8266 GW with local pulse counter sensor, no radio, no other children, development branch, v2.0.1-beta. After about 20min Domoticz shows:

Watching the serial, the error builds up over time and then boom! See attached file 0_1474217602140_LmacRxBlk Issue.txt.

Recovers after about 10min, maybe a timeout or cleanup of some sort?

I tend to agree with the suggestion in the other post about using up the sockets, but I need help with what to do about it.

Any ideas, please?

@carlyler - do you have any other hardware connected to Domoticz?
I saw this issue trying to connect two different controllers to the same gateway.

Hi sundberg84. Thank you for the reply.
Currently I just have the 1 ESP8266.
I think I found the issue. There is a a lot written online about the error and what I got from it was the ESP8266 is being asked to do more than it has time to do. Given that I was only transmitting every 10sec I started looking at what might be tying things up. From the MySensors ESP8266 example I had, naively, changed the sleeps to delays, since I did not want it sleeping. I realized that might be killing the ESP8266. So I changed the loop function to run freely and the code to be executed on interval. I have not seen the error since.

@carlyler - good to hear! Thanks for reporting back.

Hello everybody.
Today I started testing a bundle of ESP - MQTT version lib Mysensors 2.2.0 | 0x020200FF | final
I ran the stress test and after 5 minutes of requests, the ESP drops down.

I changed 3 times all equipment
As MQTT, I used different services, but the result is always the same.

Is this the problem in the chip ESP8266?

This problem was associated with sockets on ESP and was voiced a year and a half ago, but it seems that neither has changed.

Maybe I missed something, if there are answers, please tell me how to fix this error.

Are you running the default sketch? What arduino ide do you have? What version of esp8266 library are you using?
