i'm preparing full netbsd mirror. now lftp mirror with 10 processes are
doing it.

before that i tried rsync

cd /mirror_directory
rsync -azvr --delete rsync://rsync.netbsd.org/NetBSD .

and it failed after mirroring few hundred files, always with broken
pipe error in "writing 4092 bytes"..

what's wrong?

rsync should be more efficient in mirroring lots of small files
