Do you run the rsync from a snapshot or from the 'live' filesystem? The  
live one changes during zfs receive. I don't know if that has anything to  
do with your problem, but rsync from a snapshot gives a consistent backup  
anyway.

BTW: It is probably more simple for you to test if the rsync is related to  
the problem, than for other people to theorize about it here.
