Okay, now I'm getting the error:

Error putting file '/usr/local/htdocs/foo.ppt' on '': -37 LIBSSH2_ERROR_EAGAIN Unable to send channel data

The file was only partly distributed (it's 30MB but only 1.8M made it over).

I rebuilt with debugging enabled, but then the transfer worked! So I built again with debugging disabled and it went back to partial transfers. Frustrating.

I ran into this same issue a few weeks ago, but at that time we noticed that the symlink, /usr/local/lib/, was pointed at an older install. We updated it to a newer version and all was well. But now it's back, all the old files are gone, and this failure has returned.

I can produce the (huge!) log of the trace output of the successful scp if you think it will help.
