George, where did you get your stack ported ? How is it being called ? Since it is running under an RTOS, have you checked there is only one thread calling it ? Is there any other application using pbufs ? If everything is fine, can you put a breakpoint after the udp_remove() and track the udp_new() caller ? I'm not familiar with the DHCP code but it is not too hard to follow. Regards
