These are soft errors seen when a filedescriptor is reported ready for
reading but no data has arrived. If you see these a lot then I suspect
there is a problem in your socks library implementation of select/poll.

That string is generated by the FTP server. Suggest that the FTP server
has a odd notion of file size.

Perhaps the FTP server truly beleives that the file is 0 bytes long, and
responds with this size to SIZE commands as well? Squid uses SIZE on
binary transfers to find the object size to be reported in
Content-Length headers.
