Hi All,

I am using PowerTCP FTP for .NET Release 3.0.4.0 and I have the following problem:

1) I have several files on my FTP servers, which are in range from 1Kb - 20KB (works same for files < 300KB).

2) I am connecting to my FTP server using PowerTCP.Ftp and downloading these files.

3) After the download I am closing the Connection.

4) Download works OK for all of the files. My problem is that for some of the files the connection isn't being closed and the disconnect is done due to the connection timeout.

So my question is the following: why isn't connection being closed properly, because of which a timeout happens?

Below is a sample log generated by the FileZilla Server (btw. the same problem happens if I use other servers):

admin (127.0.0.1)> 230 Logged on
admin (127.0.0.1)> CWD /test_dir
admin (127.0.0.1)> 250 CWD successful. "/test_dir" is current directory.
admin (127.0.0.1)> PASV
admin (127.0.0.1)> 227 Entering Passive Mode (127,0,0,1,8,2)
admin (127.0.0.1)> LIST
admin (127.0.0.1)> 150 Connection accepted
admin (127.0.0.1)> 226 Transfer OK
admin (127.0.0.1)> 421 Connection timed out.
admin (127.0.0.1)> disconnected.

Thanks in advance.
