Welcome to the joys of debugging.  :-)  What I'm saying is "fetch -v" is
simply insufficient for a problem report.  The above should give you
some more stuff to run the next time you see it.

Since you're only seeing this problem with a single mirror, I'd
recommend 1) stop using it, and 2) report the problem to the
freebsd-hubs mailing list.  Usually the mirror maintainers hang out
there.  Possibly something is going on with the machine itself or the
surrounding network which is causing this anomaly for you (and possibly
others who just haven't noticed it regularly, re: only happens
sometimes).
