I try:
rsync -auv rsync://mirrors.kernel.org/centos/5.2/updates/i386/ .....
And get
rsync: read error: Connection reset by peer (104) rsync error: error in rsync protocol data stream (code 12) at io.c(614) [receiver=2.6.8]
And then, if I keep trying, eventually rsync 'works' and I get my updates.
What is causing this?
