When this happens, as it is during an SFTP upload, do you think
libssh2_sftp_write() was the last libssh2 function call before the timeout
triggered (it is called from the lib/ssh.c:sftp_send() function)? If so, can
you log the return code from that and see if you can detect a pattern in the
hang and what the last return code from that is?
I'm getting problems keeping everything together over email, so I created an
issue on github for this problem:
https://github.com/curl/curl/issues/3650
Can you just verify that I got the details correct? That also indicates you're
not using the latest curl nor libssh2, I would really recommend you try those
out before we continue digging.
If you want to, we can continue the debugging on over email and I can update
that issue going forward, but otherwise we can switch to working there. Your
choice!
