Please look at the logs on the ftp server. I bet there are clues there.

=>All of the FTP's are to users on one of two IP address that are
=>within our firewall.  My version of FTP (3A0) on z/VM 3.1 does not
=>have the passvie ability.
=>
=>I always get connected and signed in and I can do a CWD to the user's
=>directory.  The -5 only happens on a PUT <filename> .
=>
=>Today it happend on my own account on the network drive.  Then I
=>re-ran the VMFTP macro unchanged three more times and on the third
=>try it worked.
