Guru Meditation Error: Core 0 panic'ed (LoadProhibited)
-
I am running a FiPy with version 1.20.2.rc9. My code is reading messages over LoRa at about 1 per sec and then publishing the data to an MQTT broker at the same rate. Everything will be running fine and then at some random time interval my FiPy will crash. It might run for a few hours or only a few minutes. This particular test ran for about 22 minutes before crashing. I have try/except statements around a lot of code to see if I can catch some other error but nothing. This is the latest core dump.
