Hi,
just wan't to report that I've started to see the same thing since i  
upgraded to 4.6.p1,1.
Every night my backup server uses scp to transfer files from my box,  
and I see this:

2001:xxx::xxx:xx  port 63449 ssh2

The backup process works by first executing a pre-script, then  
scp'ing, then executing a post-script.. so those errors looks like  
they appear directly when the ssh session is disconnected.

Anyone else with clues?
