Hard fault while sending huge data through ethernet

utkarshchaurasiya36

"We are facing a hard fault issue in our code when sending a large amount of data. Occasionally, it runs properly, but most of the time, it goes into a hard fault after sending approximately 10,000 bytes. The image data we are sending is around 40 KB. Interestingly, sending 'Hello World' in a loop works successfully without any faults. I have also tried increasing the lwIP options sizes through a trial-and-error approach, but the issue persists. I have been struggling with this problem for the past 20 days and have not been able to resolve it. I am using the STM32H723VGT6 microcontroller. Please help me resolve this issue."
