Responsible-Changed-Why:
Claim ownership, since I've been looking at issues similar or identical
to this. Some questions:
(1) Could you let me know what versions of ip_output.c and tcp_usrreq.c
you're running with?
(2) Could you try the most recent patch attached to PR 102412? This is
a patch to ip_ctloutput(). I've attached it below, but the chances
are good that GNATS will mangle the patch.
