--- Comment #15 from Michael Tuexen <tuexen@freebsd.org> ---
(In reply to iron.udjin from comment #13)
I have to correct myself: I can't reproduce that locally. I just did not wa=
it
long enough such that all resources were freed again.

Can you remove all traffic from one of your production machines and let it =
sit
around for a while to see if all the TCP connections disappear and all mbufs
are freed or not?

Can you provide the output of netstat -sptcp? Maybe that gives a hint what =
is
happening and how to trigger the leak.
