Just curious if you've got duplicate suppression on in your Cyrus 
instance as this has given us headaches when attempting to use rsync -H. 
Rsync usually blows up every couple of minutes because of the overhead 
of managing the hardlinks (we're still on etch x64 with 2.6.9, so maybe 
it's been corrected in later versions).
