I got this crash after some a few request from client and not able to find out the root cause as it happen sometimes after an hour of running. The sketch will tunnel http request thru MQTT response so user will send MQTT request to the sketch and the sketch will convert this MQTT as http request and push it to TCP/IP stack and then convert the HTTP response and send back as MQTT response.
My code is based on this two libraries
