See: http://lwip.wikia.com/wiki/Netconn_receive I'm not sure why you need to call netbuf_new() and netbuf_delete(). What do you do with the netbuf you allocate? As far as I can remember there's no way to pass this in to the receive function, especially in 1.3.0. I think what is happening is: 1) You allocate a netbuf by calling netbuf_new() 2) You call netconn_recv() which gives you its own netbuf 3) You handle the data and call netbuf_delete() which frees one of the two from above (not sure which), leaving the other as leaked. 4) After you repeat this MEMP_NUM_NETBUF times you've leaked all the netbufs.
