I have added in Dennis Kuschel HTTPD server but since the last changes to mem/memp/pbuf etc I am getting the following error


Assert pbuf_free: p->ref > 0 failed at line 485 in lwip2/Src/Core/Pbuf.c


My stack trace shows

You can find his code at http://mycpu.mikrocontroller.net.

Now all the rest of my code, DHCP/UDP etc are working fine and seem stable, well I can leave it running overnight and its still working in the morning.
