426 Connection closed; transfer aborted.

Hi!

I am using FileZilla Server version 0.9.24 beta on Windows Vista (Firewall enabled - Filezilla Server allowed).
I have a problem where a connection is closed (and consequently the transfer aborted) after the connection has been established and the transfer initiated. The transfer is via the internet. From the log:

As can be seen from the log the user manages to initiate the transfer of the file successfully. Then, just short of 7 minutes later, the connection is closed and the transfer aborted. I have seen this numerous times with different intervals between accept and close (from a few seconds to more than 20 minutes).
Given that the transfer starts and then aborted at a later time indicates to me that the connection is dropped somewhere. The client in question uses a DSL line to connect to the FTP server.

I found an older post in which the poster seem to have a similar problem: http://forum.filezilla-project.org/view ... f=6&t=1370. Here the interval seems to be 10-20 seconds.

Any takes on whether the problem I experience is the same as in the linked post (maybe from the client side instead)? I.e. could this be caused by an unstable DSL connection.

Thanks in advance for any suggestions and comments on this problem!
