rsync - Oct 2006 - Rsync error:received SIGUSR1 or SIGINT (code 20) at rsync.c(231)

I'm trying to transfer   thousands of  file from a remote machine to  
my server.Every-time I do this, I'm getting  error saying "received  
SIGUSR1 or SIGINT (code 20) at rsync.c(231)".Pl. suggest me what  
could be wrong and how can I rectify this.

The command i'm using is rsync -avz --copy-links --delete  
childes.psy.cmu.edu::CHILDES /var/www/localhost/htdocs/childes  >  
childeslog &


Thanks,
Kavithaa
