Oliver,

If you're still trying to figure out why rdiff-backup is dying  
randomly, here's another theory:

Perhaps you are running rdiff-backup with a low priority? (eg, nice  
+10 rdiff-backup ...) In that case, my theory would be that some other  
CPU-intensive (or HD-intensive) process is running at that time and  
starves rdiff-backup while it is trying to compute the rolling  
checksums for the rsync algorithm. In that case, rdiff-backup wouldn't  
send enough data over the wire to prevent the connection from being  
dropped.
