--- Comment #19 from Robert Blayzor <rblayzor at inoc.net> ---
I still currently tracking this. I have found it almost impossible to manually
re-produce and I'm not sure what triggers it.

I will certainly check the next time it happens...  This may be completely
unrelated or but when I added the following sysctl knobs, the problem seems to
happen less..

net.inet.tcp.nolocaltimewait=1
net.inet.tcp.drop_synfin=1


This is probably coincidence however..
