Welcome to the joys of debugging. :-) What I'm saying is "fetch -v" is simply insufficient for a problem report.

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). -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
