Stack overflow when using Aliyun SDK MQTT (SSL/TLS)

[xiangcheng]

Hi, when i run aliyun's demo code on my ESP32 device, it runs well. But when I ingetrate it with my application code - including u8g2 lib, smartconfig, sensors etc, it will be overflow. How to fix it? Should I reduce/save RAM in my application? Any suggestion is welcome.

For Aliyun MQTT task, i use default(as demo shows) 8K stack size. How to check stack available size in ESP32?

printf("Stack free: %d\r\n", uxTaskGetStackHighWaterMark( NULL ));

Thanks. I don't like Aliyun OS SDK and its MQTT...
