Core 0 panic'ed (LoadProhibited) #150

Open Miraculix200 opened 2 years ago

Miraculix200 commented 2 years ago

Board: ESP32-S3-WROOM-1 Arduino-ESP32: v4.4.1-1-gb8050b365e

After a day or so of TCP requests (sending temperature and getting temperature as a response) every ~10 minutes I get a "Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled."

Backtrace:

EXCVADDR: 0x00000000

So it tries to load something from address 0x0, I suppose. In this line: https://github.com/me-no-dev/AsyncTCP/blob/ca8ac5f919d02bea07b474531981ddbfd64de97c/src/AsyncTCP.cpp#L838

Maybe I'm doing something wrong (e.g. not ever ending the client object, and calling stop() when it's not necessary), but maybe the code could have some if (something != NULL)

(I'm not sure what happens here, maybe it isn't even a problem with the library, but some memory problem, so I didn't try to fix it. And I'm using the standard WiFi client for the temperatures for now, waiting if it will crash again after some more days)

Edit: A week later there was still no crash, when using the client from WiFiClient.h. Though I also created a new instance of the WiFiClient every time it's needed, instead of keeping one instance around forever like I did with AsyncClient. So it's not directly comparable.
