[Arduino Mega2560 + ESP8266-01] Stopping after while

Dear All,

I find some hint to start.

@rha10 mentioned “wdt_reset” would not need If I set callback function when connection failed.
(I will refactoring after solve the problem this blocking).

In my recent guessing is “Webhook”(VirtualWrite function ) will blocking or invoke any wating something.

I blocked, and last message is “[WebHook]http://210.92.91~” and not any refresh or new message.
I reset only ESP-8266(External power supply turn on/off).
Suddenly “[2116442]\ >[14|03]x[00]9” message displayed and arduino mega reseted.

I use “virtualwrite” function to send sensor data to my local server.

(this url is webhook url).

Until now, my recent opinion “VirtualWrite” affect blocking codes. I will start “Does possible virtualwrite affect blocking?”.
