Once you shutdown the server, does netstat -na show all the connections dying off, and does netstat -m show mbuf usage dropping back to normal? If connections die off properly and the number of mbufs drops back to normal, then there is probably no leak. During normal usage, it is entirely possible to max out mbuf usage without there being a memory leak.
