Does this still happen with an updated version of the ESP32 Core for Arduino?
from basecamp.
Have not tested recently, all my projects now use deactivated OTA (handling OTA differently). I can test again, but not before well into September.

I am using MCP23017 IO expander with Esp32 for performing certain tasks. I am using the standard Adafruit MCP23017 library on Arduino IDE with a little modifications needed for esp32. Everything was working fine but from last few days I am facing the problem of esp reset. The following message appears on Serial Monitor

Please tell me proper reason for this problem or the way how to troubleshoot this?
from basecamp.
I am also repeatedly getting "Guru Meditation Error: Core 0 panic'ed (LoadProhibited)" errors on boot after a deep sleep with Basecamp. This started to happen after I updated the ESP platform to 1.6.0.
Building with -D BASECAMP_NOOTA=1 has solved the problem for me so I think @tobiasisenberg is right, it's an OTA issue. I also get the same backtrace, in case that helps.
