I guess you're either using scp or ssh to execute remote commands?
We've the same issue on our Solaris boxes. The only workaround we
found so far was to comment out the error(..) statement responsible
for the output of the above line.
It's located in nchan.c in the chan_read_failed() function.

I'm sorry but I'm not at work, otherwise I could supply a diff.

HTH anyway,
Christian

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:

Mar 23 21:00:04 elfi sshd[76875]: Accepted publickey for root from  
2001:xxx::xxx:xx  port 63449 ssh2

for istate 3

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?
