Downloading very large files

Question

Hi Guys

When downloading very large files (5Gb), the control channel eventually drops out. When the download is finished some 7 hours later and I try to delete the file, the lack of control channel throws a non connection error.
Fair enough. I can re log on , check file size etc and delete but is there a way to change the timeouts for this so it doesn't disconnect?


cheers

Answer 1

This is normally because the server closes the control channel, so there's not much you can do about that. It's really a server security feature to stop users monopolizing connections. You may be able to change the server timeout, but it'd have to be set very high. (Usually 300 secs or something like that).

Thanks Bruce

Didn't think there was anything I could do about it. Guess its back to the re-logon, check and delete which is a pain when dealing with concurrent transfers :-)

There was supposed to be a fix of this issue in version 1.2.3 with the ServerWakeupInterval property as mentioned in this thread:

Or by using the workaround in this thread:

Or is your problem different from the one outlined in those two threads?

Unfortunately most servers can't cope with the server wakeup or keepalive suggested below - the server just gets confused.
