Rich,
Do you have access to the FTP server logs as this could possibly tell
you
whether the connection is being dropped or not.

Yea, I tried that, but thank you anyway.
I think it might be related to keepalives. In the code, the cached FTP
connection is initialised at the start of the script so that it can
delete
any remote XML files that may exist before uploading a new one.
The script then goes about its business, creating the new XML, and then
the
PUT operation is executed to upload the new XML. Like I mentioned, this
worked fine in CF7, and the script ran slower in CF7 than CF8.
However, in CF8, it looks like the connection has died by the time it
gets
to the PUT operation. I confirmed this by moving the cached connection
initialisation closer to the PUT operation, so there was no middle
script
actions to introduce any delay between creating the connection and the
PUT
operation. What do you know, the script now works fine and the FTP PUT
doesn't report in a timeout operation (surely if the connection had died
the
error should be different).
So what's going on here? The cached connection initialisation had by no
means hit its timeout value (set to "99999", and there's only about a 20
second gap in the actual start and end of this script, when it was
erroring), so surely CF server is sending keepalives to the remote
server
to
keep it open? CF7 must do this if it was working fine...
Very confused. At least I have an answer, but I'm confused as to this
seemingly backwards step between 7 and 8.

The default timeout on the cfftp command is 30 seconds - I know it
shouldn't
have changed but might be worth playing with that attribute?
