Hello,

First time I have ever seen this issue, I am running 2.6.31 x86_64 & lftp:

$ lftp --version
LFTP | Version 4.0.2 | Copyright (c) 1996-2009 Alexander V. Lukyanov

I ran: lftp -f script where script downloads some files and then this occurred:

The lftp process was running in a screened session.

Any thoughts as to the bug here?

Justin.
