ESP8266 gateway crashes while the node is in FOTA progress.

Hi there,
I recently started using the library and i wanted to use firmware OTA feature. However I'm getting error at gateway whenever the node requests firmware OTA update. I can see from gateway logs firmware OTA is initiated and data is exchanged between the gateway and node, but unfortunatelly the gateway crashes every time and resets. I appreciate any help as I have spent many hours but couldn't find a solution yet.

Setup:
Gateway : Wemos D1 Mini + RFM69
Node : ButtonSize Node (a custom Arduino Pro mini + RFM69 + Flash + Dualboot)
Controller: MyController
Transport: MQTT
Power : Through USB port from the computer for both gateway and node

It seems a watchdog reset. Try increase the timer before the watchdog resets the chip

@gohan thanks for the suggestion. Would you mind giving a code example please. I don't; know much about the esp8266

I don't know much about the esp8266 watchdog too... Sorry

@gohan I've added ESP.wdtFeed() and tried with another memos d1 mini + rfm69, but it didn't help, still getting ets Jan 8 2013,rst cause:4, boot mode:(3,6) message.
@yury / @Koresh do you have any idea about it ?

After upgrading Wemos from 2.3.0 to 2.4.0-RC2 version, OTA works well know
