Hi,
just wan't to report that I've started to see the same thing since i =20
upgraded to 4.6.p1,1.
Every night my backup server uses scp to transfer files from my box, =20
and I see this:

Mar 23 21:00:04 elfi sshd[76875]: Accepted publickey for root from =20
2001:xxx::xxx:xx  port 63449 ssh2
Mar 23 21:01:18 elfi sshd[76875]: error: channel 0: chan_read_failed =20
for istate 3
Mar 23 21:01:18 elfi sshd[76875]: error: channel 0: chan_read_failed =20
for istate 3
Mar 23 21:01:18 elfi sshd[77389]: Accepted publickey for root from =20
2001: xxx::xxx:xx  port port 63450 ssh2
Mar 23 21:53:31 elfi sshd[77389]: error: channel 0: chan_read_failed =20
for istate 3
Mar 23 21:53:32 elfi sshd[77389]: error: channel 0: chan_read_failed =20
for istate 3
Mar 23 21:53:34 elfi sshd[85742]: Accepted publickey for root from =20
2001: xxx::xxx:xx  port  port 49493 ssh2
Mar 23 21:53:34 elfi sshd[85742]: error: channel 0: chan_read_failed =20
for istate 3
Mar 23 21:53:34 elfi sshd[85742]: error: channel 0: chan_read_failed =20
for istate 3

The backup process works by first executing a pre-script, then =20
scp'ing, then executing a post-script.. so those errors looks like =20
they appear directly when the ssh session is disconnected.

Anyone else with clues?
