Environment

Novell NetWare 6.5 Support Pack 6
Novell NetWare 6.5 Support Pack 7
Novell NetWare 6.5 Support Pack 8
NetWare OpenSSH (SSHD.NLM)

Situation

Cannot upload or download files larger than 2 gigabytes to a NetWare file server over an SFTP connection (SSHD.NLM)

File transfers using SFTP via SSH fail at 2.0 GB.  During a download, SFTP clients may show an error such as:
 
Couldn't read from remote file "/server1/vol1/file1" : No such file or directory
 
After a failed upload, errors may occur in sys:etc\ssh\logs\sftp-server.log similar to:
