A problem has been identified:
I've got what I need, I see the problem in our FTP server code. What triggers
the problem (and why it shows up intermittanlty) is that the one particualr
client issues the append command to our FTP server and our server than attempts
to open the data connection

Another question, is there any time in the append process where, by
design, the record count appears to be zero for even the briefest of
periods? In other words, is there a window that has a crack in it?

I meant MVS systems. We only have VM at one location. TRACERTE is
disabled between the network where VM resides and the non-MVS systems at
the centers where the FTPs originate, so I substituted the MVS system
in the center in question. Not a perfect fit, but

Richard,
What about, just for diagnostic purposes, having location A FTP the file
three times.
1) FTP it to a discrete/unique file id (maybe with the filetype as rexx
time('S'), seconds since midnight with an 'A' suffix, like 12345A. Save
the 's'
2) FTP APPEND as you are now.
3) FTP again

Would putting CP TERM TIMESTAMP ON in the PROFILE EXEC or if CP 5.3.0

Hi, Richard.
Since it is only one file from one site that is causing the problem,
would it be possible that someone, at the remote site, is accessing the
PC directly and doing a manual FTP PUT, instead of an APPEND? Could this
simply be operator error on somebody's part?
Schuh, Richard
on the next attempt to do the FTP
APPEND
after this error, whatever it is. There is no mention of ?FTPDATACONN?
in the
5.2 TCP/IP bookshelf.
That error message is from the PC client in response to a server error,
not VM. You need to see the error generated by the VM FTP server.

Well, other than discovering what that illusive error message is, I'm
fresh out of ideas here.
