Thanks, Ketul From: Ketul Barot Sent: Tuesday, March 05, 2019 10:25 AM To: libssh2-devel@cool.haxx.se Subject: RE: SFTP transfer hangs when the server connection has high latency RTT around 500 ms and 30% packet loss Hi, For some reason I am not able to reproduce the hang with sftp_write_nonblock.c but I did find the same thing happen with the curl. I have enabled the debug option and added the libssh2_trace as mentioned by you. Attaching the log file. It has both libcurl debug messages & libssh2 debug messages. Please take a look at the log file and I will try again to reproduce the hang with sftp_write_nonblock.c example. I will send the debug log for that once I reproduce the issue.

Ideally build the current libssh2 master code with debug messages enabled, and add a call like libssh2_trace(session, ~0); in sftp_write_nonblock.c maybe after the libssh2_userauth_ calls, before the first libssh2_sftp_ call. Then send the full output from that program for a run where the error happens to the list. Please log to a text file and attach that file to your mail, so that all information is kept intact.
