Net_sys_error : ERR_MEM_CORRUPT

Hello,

We are currently working on a Web server on an ARM Cortex-M7 to transmit JSON string via HTTP and CGI.
When sending TCP / IP packets (2 or 3 TCP segments), an error occurred: net_sys_error NET_ERROR_MEM_CORRUPT.
This error occurs randomly after X send TCP / IP packets.

Before the error occurs, the HTTP server sends only one TCP segment (1440 bytes) instead of 3 TCP segment (2989 bytes).
We can not find the cause of the problem.

Card:
STM32F769I

Versions:
HTTP_Server_FS.c: v7.2.0
HTTP_Server_CGI.c: v7.0.0
Net_Config.c: v7.7.0 (variant IPv4 / IPv6 Release)
Net_Config_HTTP_Server.c: v7.0.0"
