It looks like the rsync server on cygwin is failing to

I know (from prior offline discussion) you are using ssh key
based command restriction via a wrapper script on the linux
rsync servers.  Are you using a ssh key based command
restriction here as well?  You don't mention that anywhere
in this email.
I am using an authorized_key, but no command restriction on the windows
server.
If you are running rsync via a wrapper script does the
script exec the rsync command or run it as a child process?
No wrapper script.  So rsync is a child of the ssh process.

Ahh, write didn't complete.  We have an i/o error outside of rsync.
Where do I go from here?  I did an strace of the cygwin ssh process on
another rsync (same command), here are the last few lines:
