--- Comment #115 from Richard Scheffenegger <rscheff@freebsd.org> ---
The stacktrace here looks entirely different, with the local system's tcp s=
tack
not being involved (as this is a router, forwarded traffic doesn't normally=
 get
processed by the tcp stack - only by the ip layer as is visible in the stack
trace).

I suggest to open a separate bug for this, and also provide the core dumps =
if
possible (note that the core dumps may contain sensible information in the =
mbuf
chains).
