Comment:
I don't think it has anything to do with the openssl version.
At line 460 in your log file, we can see how the error at code line
src/sftp.c:629 is reached. The question is what 'rc' contains at that
point!
Also, as can be seen in that function there's a bad assumption that
_libssh2_channel_write() will either return PACKET_EAGAIN, send the entire
packet or fail. There's also the chance that it simply sent a piece of the
packet and thus have to send the rest of the packet in a second try. I
suspect that is what happening for you.
Seeing the error code as I mention above, might help us verify this.
If that is indeed the case (and really, even so if it isn't), then we
should fix this function by keeping "number of bytes already sent" in a
variable and allow the state machine to get back and send the rest of the
packet at next oppurtunity.
