Just wanted to confirm - no firewalls on either machine, even Windows'
own firewall is switched off.

The symptoms (works with small files, not with larger ones) would seem
to imply that ftpd is trying to write all 215MB in one go.

And why, exactly, did you send your reply to another mailing list?
Especially one dedicated to hippos and definitely *not*, I would like
to stress this point, *not* dedicated to Cygwin.  Not exactly dedicated
to Cygwin.  More or less.  Not without mentioning hippos anyway.
