I have tried using online ESP decoder …it is giving me following details:

  • 0x4027ce8d: mem_malloc at /local/users/gauchard/arduino/arduino_esp8266/origin/tools/sdk/lwip2/builder/lwip2-src/src/core/mem.c:210

Any help would be great :slight_smile:

most likely out of memory condition
check available heap prior to crash

Your only remedy is HW upgrade. ESP32
