Error: "not a plain file"

Greetings:

I've looked and looked...  Found lots of source code examples of this
message and even a few questions like this - but no answers.

I have a client  that is trying to upload a <file>.tar.gz to a wu-ftpd
FTP server.  The local ftp client (dunno what it is just yet) is
showing this error:

> > > > Using binary mode to transfer files.
> > > > ftp> bin
> > > > 200 Type set to I.
> > > > ftp> cd from_cust

> > > > local: to_ae_0112.tar.gz remote: to_ae_0112.tar.gz
> > > > to_ae_0112.tar.gz: not a plain file.

I'm not sure if this particular error is from the client or server.  (I
think from the server) but the funny thing is that if we try this exact
sequence a second time in the same session, the transfer succeeds.

The really puzzeling thing is that in my years of administering this
particular server, I have never seen this error before.

Any thoughts on what might be causing this?  And how to fix?

Assist will be appreciated.
