This behavior doesn't happen when connecting to all ftp servers. I've noted it connecting to an Ipswitch MoveIT server but not to plain vanilla UNIX/Linux ftp servers. I've programmed around the problem in my shell scripts by listing the file first and having the shell script decide what to do with the file if it's zero length. (In my case I simply delete the file from the server, log the fact that I did it and move on.)

I've noticed other odd behavior in the interaction between my MoveIT server and curl. Curl versions after 7.19.4 seem to have trouble sending files > 16k to the MoveIT server. Prior to 7.21.3 curl didn't even report that the transfer failed. Now, at least it does that much.

I've always thought that this odd behavior must be related to something odd with MoveIT because the same versions of curl don't have these problems on any other ftp server I've tried.
