How much ram and swap do you have in the machine.

Before you run the "mirror" program I would say get yourself around the 
50meg of swap and 16meg of ram at minimum.

I just hashed the ftp.debian.org into ram and it lookes like about the 
80meg of virtual ram range.

I would suggest that at a minimum a 32meg ram machine and 80meg swap or 
better to do the whole mirror at one time. I would also suggest that you 
break up the mirror into subdirectories of the main archive so that you 
can get smaller chunks of the whole thing. You may find this useful 
anyway since the link from us to you is very instable anyway.

Just a few ideas / chatter
