Is that client OSX, server OSX or both?

What happens if you run the client on Solaris and the server on OSX?

What about another FTP Client (e.g. one that comes with the OS) - does
that work OK?

The error looks more like a server issue rather than a client issue -
perhaps there is a TCP stack configuration problem on the server.
