This has been happening to me in environments with high packet loss, 
and before the NewReno changes went in.  It was only happening in a 
rather dubious environment were there was high packet loss 
(compressed PPP over uncompressed PPP over a saturated ISDN dialup 
that drops up to one in every three packets).

There were other bugs involved too - see recent updates to nat_cmd.c, 
so I never really took the whole thing too seriously (apart from 
suggesting to root@freefall that they shouldn't worry).

I'm still seeing these errors:

  ipfw: -1 Refuse UDP in via tun1 Fragment = 185

But haven't looked into them too deeply for the same reasons.

All I'm saying is that I wouldn't suspect that the problem is 
entirely NewReno but rather that the NewReno stuff may be irritating 
some other problem(s).
