degenerate
This happens with all SmartFTP 4.x versions I have tried.
I regret that I am unsure if this is a SmartFTP or ProFTPd bug, because I upgraded to 4.0 of SmartFTP at the same exact time I reinstalled the control panel on my server. So hopefully this is enough!
The problem
Every time I transfer a file from my local machine to the FTP server (or from server to local) the file is added to the transfer queue with "retry". Then approx 20 seconds later the file finally transfers. I can then transfer anything within the next 30-60 seconds. However if ~60 seconds goes by, any file that I want to transfer is again added to the transfer queue with "retry".
Here is the log in one of the files in the transfer queue when it says "retry"
Then it finally transfers after 20 seconds, and here is the full SmartFTP log. As you can see there is no indication of anything wrong...
******************** THEN AFTER THE FILE FINALLY TRANSFERS....
And here is my ProFTPd 1.3.2 configuration.............. note that this proFTPd is part of "interworx" control panel.
