Yes. I have tried same test-case with ESP32 IDF 3.1 Stable Release and didn't face that type of issue yet. I have checked almost 15+ times with same type of firmware by changing ESP32 IDF from 2.1 to 3.1 which works well without any issue.
But, Right now, I have already delivered few products and prototypes to customer and I want to resolve that issue into ESP32 IDF 2.1.
I know there might be some fixes into LWIP level to resolve that issue which might be fixed into ESP32 IDF 3.1 and Right now We can not switch our firmware from ESP32 IDF 2.1 to ESP32 IDF 3.1
So, Espressif SDK Developer might have better idea regarding this issue and they can help me to resolve that issue into ESP32 IDF 2.1.
Still, I will try to just port LWIP component from ESP32 IDF 3.1 into my existing ESP32 IDF 2.1 will provide results with that.
