Alpha DS25 cannot FTP

[Winson_1]

My Alpha DS25 OpenVMS V8.2 is having intermittent connection issue with FTP service to another VAX running Multinet TCP/IP or Windows XP FTP server. I get this FTP timeout message:
FTP> connect x.x.x.4
%TCPIP-E-FTP_NETERR, I/O error on network device
-SYSTEM-F-TIMEOUT, device timeout
FTP>

If I do make a connection I’m able to login; when I perform directory listing I get error below:
FTP> dir
200 Port 192.18 at Host x.x.x.101 accepted.
150 List started.
%TCPIP-E-FTP_DATACONF, cannot establish data connection with remote host
-SYSTEM-F-CONNECFAIL, connect to network object timed-out or failed
425 Can't build data connection: %MULTINET-F-ETIMEDOUT, Connection timed out.
FTP>

The Alpha can FTP to itself and perform directory listing with no problem. The other VAX can Set Host or Telnet to the Alpha system with no problem but cannot FTP to it. All of these systems are connected to a switch and behind firewall. I tried both passive FTP ON/OFF with no success. Am I missing something in the TCPIP configuration?

Here a FTP service listing:

Is there anything interesting in the log:

$ type SYS$SYSDEVICE:[TCPIP$FTP]TCPIP$FTP_RUN.LOG

TCPIP$FTP_RUN.LOG:

Ouch. An access violation in a server process is not good. If the system is under any kind of support contract, you really should log a call. They will want to know if you've applied all available patches. There is an ECO for TCP/IP v5.5 as well as some system ECOs.

Patched the Alpha with the following:

DEC-AXPVMS-TCPIP-V0505-11ECO1-1.DCX_AXPEXE
VMS82A_UPDATE-V0100.PCSI-DCX_AXPEXE
VMS82A_SYS-V0200.PCSI-DCX_AXPEXE

Re-installed OS and FTP works fine afterward. DS25 system came with pre-installed OS might be the problem.
