Increase in errors: Could not rename Temporary Download File

[anjackson]

This stems from:

w3act/app/controllers/Documents.java

Line 325 in 6ad35ff

FlashMessage error = new FlashMessage(FlashMessage.Type.ERROR, "Could not rename the temporary download file.");

Not clear why it's happening. Most likely is that the destination already exists, and if so, that should be raised as a separate error.

More logging would be helpful, to track if renames appear to fail. e.g. to include the SIP IDs.

Could have been a race condition, between users accidentally working on the same items. Will ask for some example IDs.
