tFTPPut failed when transferring files from local to remote server

[Anonymous]

I am trying to copy the directories and files from my local computer to a remote server. Here is the job design:

I copied the directories from local to remote server with tFTPCreateDirectory -- There are 255 folders and subfolders created in total.

Then I used tFTPPut to transfer the files from the local directories to their matching remote directories.

As you can see, it failed after 249 executions finished, the time the job was almost about to complete.

Here is in the destination folder where the job failed at -

The files were listed in alphabetical order in both remote and local folders.

Remote Destination folder: All other files were updated @8/14/2018 9:20 AM except the last one.

Corresponding local Source folder:  I don't see anything wrong or special with the very last file.

I ran the same job again and it failed at tFTPPut when 26 executions were finished this time. (I didn't make any changes to the job and the local source is the same).

Please help me find out why the job would fail. Thanks!

Found out the problem.

There is nothing wrong with the job.

The process cannot access the file because it is being used by another process.
