    Hi Alexandre,
     
    I once had a similar problem with sending files from our IBM mainframe (VM) to AIX.
    Ours was caused by TCP/IP keeping too many connections open till all possible connections were exhausted.
    Have a look at netstat -a (or something similar) and count the number of connections in state "CLOSE WAIT".
    If I remember correctly this connections wait about 5 minute before they are closed.
    I think we solved the problem by reducing the wait time.

            Hi Guru's
            
            I'm using some batch jobs that send some huge files (around 40GB or more) to a Windows server. At some point of time (not specific), the job is aborted. I'm having some troubles, because it is necessary to run those jobs again and I spend much of time. The Windows support team searched for some related problems and there's no issue regarding AIX to Windows FTP transfer. The network is also ok.
            Does anyone have some clue about what is happening?
            
            Connected to XXXXX.
            220 XXXXX Microsoft FTP Service (Version 4.0).
            331 Password required for YYYYY.
            230 User YYYYY logged in.
            200 Type set to A.
            250 CWD command successful.
            250 DELE command successful.
            200 PORT command successful.
            150 Opening ASCII mode data connection for USU00000.
            426 Connection closed; transfer aborted.
            225 ABOR command successful.
            350 File exists, ready for destination name
            250 RNTO command successful.
            
            Best Regards!
            
            Alexandre
