I don't recognize that 'unknown host' log entry. If the transfers
wait for whatever is writing it, it might cause a delay where the time
will depend on the DNS response - if you get an immediate NXDOMAIN
from a local server it should be quick but if you are referred to an
upstream and possibly firewalled server that won't respond you would
have a multiple-second wait for a timeout.
You could test the theory with "nslookup 172.17.0.1" to see how long
the response takes if that is the actual address.
