OpenVMS 8.2 FTP command stops working

[gpaytonbham]

We are currently running OpenVMS 8.2 on a DEC Alpha server.   We have just stared having a problem where the server will no longer ftp files.   All TCP/IP services are still running, and stopping and restarting the TCPIP$FTP service does not work.   The only way to get FTP running again is to reboot the system.  

In the TCP$IP_RUN.LOG  the following error message occurs:

%TCPIP-I-FTP_CHINFO, TCPIP$FTPC00001: Failed to send data on socket
%SYSTEM-F-IVCHAN, invalid I/O channel
%TCPIP-I-FTP_NODE, client host name: 10.50.3.58

How do we solve this problem, and is there a way to get FTP running again without rebooting the system.

Any help or suggestions would be appreciated.

Thank you.

Let's start with some basic information. Please post the output of

$ TCPIP SHOW VERSION/ALL

$ TCPIP SHOW SERVICE FTP/FULL

$ SHOW SYSTEM/PROCESS=*FTP*

It may also help to see what errors (if any) you get from an FTP request back to yourself:

$ FTP 127.0.0.1

(with appropriate username and password).
