I did this

Executed below command to sftp a file:
curl -k -u user_id:password -B -T <source_filename> sftp://<remote_host>/<target_direcotry> -m 120

I expected the following

When target_direcotry is full on the remote host, the curl command getting hung forever. -m --max-time 120 is not working

curl/libcurl version
