Can't Figure out why rsync job stops

[Jim Salter]

Have you fsck'ed the filesystems on both ends?

Have you checked to make certain network pipes don't get magically 
broken in between both ends?  (Many connections have issues in which a 
given pipe will only stay open for [x] amount of time, or [x] amount of 
idle time, before being closed by a router.  This is not an issue which 
tends to be visible to the end-user with protocols like HTTP or FTP, but 
can very definitely be an issue with SSH or rsync.  Test: ssh across the 
two servers.  Do nothing for half an hour.  Is the pipe still open?)
