Correct.  It happened after some number of connection.  Using "lsof", I 
could not see any that limits were being realistically hit, either.

Unfortunately I have just one ipv6 freebsd 7 machine to work with :-( and 
mail is supposed to be a production service.  I'll have another 
opportunity to do more on June 14, when downtime is scheduled for 
another location.  At that time I'll get that location's OS updated, onto 
ipv6, and since it is just two (flexible) people, I'll have more room to 
play.
