Timeout...

Synchronizing from a remote to local server using an automated script and I'm getting a "timeout detected", End of Log:

We've previously used CoreFTP for several hours, so I don't think it's the remote server kicking us off
I then added a -timeout to the script:

open ftp://user:pass@server/ -timeout=500

15 was the demonstration value given, I tried that and then bumped it up several time until I got to 500, it didn't seem to matter what I set it out. Do I need to call this differently or try keepalive? What is the appropriate way to use keepalive?

Re: Timeout...

The "Timeout detected" message is nonsense. It's a bug. Added to tracker:
https://winscp.net/tracker/1197

The real issue there is that a server closes a connection.
It can be because of the -a switch of LIST. That's very common. Though WinSCP should try to reconnect and use pure LIST. Unless you are using some ancient version of WinSCP. Can you attach a complete log file?

It's a slightly difference scenario this time:

< 2014-07-29 13:08:43.802 Script: Timeout detected.

Though the root cause is still the same, the connection with the server was lost. I'm not sure how to help you further.
