ESP8266 crashes while starting up and receiving a message from node

[Abdu Sahin]

Hi there,
I have successfully setup a sensor network with MyController, Wemos D1 mini (Mqtt GW) , Arduino and RFM69, and it normally works fine, but sometimes I start Wemos D1 mini, then it immediately crashes, It happens only when a node sends data while Wemos GW is starting up.
I suspect it's happening because gateway tries to send the message to the controller while not connected to the WiFi yet.
Is there a way to not process messages from nodes while gateway is starting up, so gateway would ignore node messages until it's initialised.
