Hi
By check
http://www.lpcware.com/content/faq/malloc-failure-using-freertos-heap3c-lpcxpresso-tool-chain
I found that heap is real overfollow once more request coming in frequency. More memory is not free on time.
In real application, FreeRTOS and LWIP also use C lib malloc and free function in case of
1.
Freertos use heap3.c
2.
popt.h define
#define
MEM_LIBC_MALLOC 1
#define MEMP_MEM_MALLOC 1
How to fix the issue of heap overflow ?

Hi:
I define following to use system malloc and free
#define
MEM_LIBC_MALLOC 1
#define MEMP_MEM_MALLOC 1
I found that the malloc memory is not free on time, so malloc failure in new request coming.
It seems to need some protect those . Am I right ?

Subject: demo web refresh down
All:
I use LPCXPRESSO to develop a simple demo server with NETCONN api on LPC1769
If the demo server refresh itself per 3 second, it works well.
If I refresh it by press F5 frequencely, it halt and can’t connect to host..
Who know the reason ?
