After a long time debugging with strace I'm ready to give it up.

I get the following in my logfiles
----
daemon.warn: Jun  2 16:15:22 rsyncd[3157]: rsync: connection unexpectedly 
closed (0 bytes received so far) [receiver]
daemon.warn: Jun  2 16:15:22 rsyncd[3157]: rsync error: error in rsync 
protocol data stream (code 12) at io.c(420)
----

But from cron also the following mail
----
opening tcp connection to rsync.uribl.com port 873

So it looks like he is just working as expected. But why the message in the 
logfile?
I have a strace of with and without invoking from cron and I don't see a 
difference.

Could somebody tell me what the message in my logfile means?

With kind regards,
Met vriendelijke groet,
