Problem rsyncing 450GB file to my NAS: 'connection unexpectedly closed'

Hi list!

I'm trying to use rsync to do a regular remote backup of a 450GB sized 
container file located on my squeeze server onto a colocated QNap NAS 

Both use rsync 3.0.7. While this setup works for most files, it fails on 
this large file (see log below).

I'm already trying to help rsync using "-P" to indicate that rsync 
should reuse the current copy and not trying to create a copy on the 
/tmp parition of the NAS.

Any hints what might be the problem?
