I'm not sure.  Are you saying the pbuf's have a reference count of 0 but
they are not freed?  Are you sure this is the case for all the pbuf's in
question?  Which interface are you using to access the lwip stack (the raw
API, sockets, or something of your own creation)?  I think we'll need some
more information to help you with this problem.
