--- Comment #5 from Hiren Panchasara <hiren at FreeBSD.org> ---
Adding Michael for inputs as he had done some cleanup in this area.

What FreeBSD version are you running on both sides? Is it 10,3R as reported in
the bug? Do you mind trying -head to rule out any fixes?

Server sends FIN and on the following request sends RST which gets dropped
somehow and doesn't reach client. But even after receiving first FIN, client
asks for data to which servers reopens the connection (which seems like the
real bug), sends data and again sends FIN after that. Now client acks that FIN
and sends its own FIN which server acks but client now doesn't like it. So it
keeps sending FIN which server keeps acking.

Also, client and server seem off by 10seconds?
