openssh unix dev - Aug 2016 - sftp fails with error Received message too long 140013605

Hi.  When I try to sftp to a client, which is an embedded Internet of Thing
(IoT) system, I get the following error:

jeff at SQA-ip6-tester:~$ sftp -6 root at SpeedwayR-10-28-25.sqa.impinj.com
Password:
Received message too long 1400136052
jeff at SQA-ip6-tester:~$


The error also occurs with IPv4

jeff at SQA-ip6-tester:~$ sftp -4 root at SpeedwayR-10-28-25.sqa.impinj.com
Warning: Permanently added the ECDSA host key for IP address
'172.31.14.164' to the list of known hosts.
Password:
Received message too long 1400136052
jeff at SQA-ip6-tester:~$

I did some googling, and I found
http://askubuntu.com/questions/369830/sftp-connection-failed-strange-error-messsage
which says that I should look at  http://www.openssh.org/faq.html#2.9), which
now 404s. I looked through the wayback machine.  On April 23rd 2016, it did a
302 redirect which failed.  I did find it at
https://web.archive.org/web/20160203202936/http://www.openssh.com/faq.html<https://web.archive.org/web/20160203202936/http:/www.openssh.com/faq.html>
I followed the instructions and got some text, which I assume is the source of
my problems.

Please bring the FAQ back - it is useful!

Hi Jeff,
>>> hex(1400136052)[2:].decode("hex")
'Stat'

Looks like sftp is sending an error message that starts with "Stat".
You
may try to manually reproduce this with ssh -s sftp.

I'd like to, but most of it was so rotted by the passage of time as
to make the document useless. If someone wanted to collect a good set
of FAQs that are current and relevant then I'll see about getting it
committed to the website.
