This time I let it run until it wrote 100% of the image. Then it
started to download files in some random, at least non-alphabetic
order. After the first 10 files there is this message:
FINISHED --16:15:24--
Downloaded: 4,462,916 bytes in 10 files
Found 10 of the 5042 files required by the template
which indicates to me that it wants to download 5042 of the 6720 files
required by the template. Of course I stopped it again.

I compared the files downloaded to a tmp directory with the ones of my
mirror and found them to be identical:
$ cd ./sarge-i386-1.iso.tmpdir/gluck.debian.org/cdimage/snapshot/dvd/i386/Debian/pool/main
$ find -type f

I first tried with a two week old jigdo-file-cache.db in the same
directory. Next time I deleted it prior to running jigdo-lite, both
with the same result.

$ jigdo-file --cache=jigdo-file-cache.db md5sum /pub/mirrors/ftp.debian.org/debian/pool/main/a/adduser/adduser_3.59_all.deb
K3IwZGUJlF7q6sCv7t8PfA /pub/mirrors/ftp.debian.org/debian/pool/main/a/adduser/adduser_3.59_all.deb
$ jigdo-file md5sum /pub/mirrors/ftp.debian.org/debian/pool/main/a/adduser/adduser_3.59_all.deb
K3IwZGUJlF7q6sCv7t8PfA /pub/mirrors/ftp.debian.org/debian/pool/main/a/adduser/adduser_3.59_all.deb
Both checksums look the same.

The mirror is on a ReiserFS on kernel 2.6.8.1, kept up-to-date by a
modified debmirror. Purging is done by own script with 90 days
latency. The mirror logs show no problems.

Yes, I use that version since July 6th.
