[10053] Software caused connection abort with FTP transfer

I’ve been getting problems with some file uoads, but not others. The problems are fairly intermittent. The files are being created localy ok, but not always uploaded. I took a look in the ftp log and found this error;
[10053] Software caused connection abort with FTP transfer

Any idea what the problem may be?

I’m also seeing this in the ftp box;

No more files to upload
All Agenda complete, doing FTP log off…
FTP logoff
QUIT
221-Goodbye. You uploaded 206 and downloaded 0 kbytes.
Disconnected: [10053] Software caused connection abort
FTP error occured
FTP error, looking for next agenda item
221 Logout.
Doing abort procedure/program close…
Will stay connected…

It seems to be quitting before it’s finished.

I also noticed that some times I get 2 instances of ftp running and uploading the same files at the same time.

try increasing the ftp time out and overall ftp time out in the connections setup
but also the problem can occur by a ftp disconnect when your isp is busy,etc

I’ve done that. There’s no problem with slow connections to my server. Also some files are always getting uploaded, but others aren’t - always the same ones. This has only started hapening the last couple days. I have also reduced the number of files being uploaded incase that was the problem.
