Upload successful but zero bytes in file

[bryanpearson]

When transferring files larger than 10MB to a PureFTPD
server (Version 1.0.20-7 running on Suse Linux
10.0)upload is successful (according to logs) But the
file length is zero bytes. This appears to happen less
often with smaller files, but almost always with files
of 100MB or more. The newest version seems to do it
more than older versions. It will resume properly if
interrupted, but is just as likely to create zero
length files. I am including the entire log file
generated during these transfers.

I haven't found another client which does the same

thing. If needed, I can provide a network packet
capture or try it again with various settings if it
will help. This problem seems to occur whether active
or passive, and through two different firewalls
(Symantec Enterprise and Smoothwall) or through no
firewall.

This problem seems less likely to occur with passive transfer.

Improper client configuration paired with malicious
firewall/router it seems. Not a bug in FileZilla.
