WS FTP Server v6 and zlib

We recently installed v6.1 of the server in order as part of a consolidation project.

the problem is that one of the clients being migrated generated the following set of messages at the client end.

based on the context, I took a very wild guess and enabled zlib compression on the server. It seems to have worked, but now I'm concerned that other clients may have trouble connecting if they are not using zlib compression.

any thoughts on that? Was my solution the correct action to take?

thanks.
