Version: 4.3.1, OS: AIX PPC. Protocol: SFTP We have been testing lftp with large files (>2GB) and notice the transfer hangs after 2GB:

Based on this response http://www.mail-archive.com/lftp@uniyar.ac.ru/msg00994.html: By default, lftp tries to use large file support of the operating system if it is available. It is also important that the ftp server also supports large files. We verified that /usr/bin/sftp can transfer a 3GB file so I assume this means the OS supports large files. Can we safely conclude that our copy of lftp was compiled without largefile support (e.g. configure --disable-largefile)? Thanks, Jimmy
