- I not using calloc and malloc
- We use netconn to create webservice, when I “send” big file over netcom_write (split the file into 1k as shown).
- Sometimes I can send the file multiple times before the program stops but sometimes it stops on the first send
- This is content of the sys_arch_sem_wait

Just some questions, that might Help to track down the issue:
Is your memory Handling OK? Are the buffers freed after use? Are you using permanently malloc to create a Buffer or do you have a Buffer Pool?
BR, Axel

Dear lwIP Support Team,
Thank you for your response.
To provide more details, I am using the STM32H573VIT MCU. It features a Cortex-M33 core, 2MB of flash memory, and 640KB of SRAM. For Ethernet connectivity, I am using the RTL8201F Ethernet PHY. Additionally, I have integrated an external flash memory with a capacity of 16MB for handling larger data storage needs.
As mentioned earlier, I encounter an issue when sending large web data files. After splitting the data into 1KB packets, the transmission works initially, but after a few webpage reloads, the MCU crashes after sending a few packets.
I would appreciate your guidance in identifying the root cause and any suggestions for resolving this issue.
Thank you for your time and assistance.
Best regards!

Dear lwIP Support Team,
I am currently working on a project using LWIP with RTOS to send large web data files. However, I have encountered an issue where I am unable to send the entire file at once. To resolve this, I divided the file into smaller packets of 1KB, which allows the transmission to succeed.
While this approach works initially, after reloading the webpage a few times, I experience a problem where the MCU stops responding after sending only a few packets. The transmission fails, and the program halts unexpectedly.
I would greatly appreciate your assistance in diagnosing and resolving this issue. Could you please guide me on possible reasons for this behavior and suggest any potential fixes?
I attached the lwip config file
