Thanks for replying @Thomas But my device have limited memory. I am able to use 16K memory so have defined it
#define MEM_SIZE (16 * 1024). Also my lwip not crashes but just lost the ping from other device. Any other way to overcome this issue? Can we force the upper layer to Free all buffer? For solution i have keep highest priority for TCP/IP thread but no luck.
