Frequent error with scheduled data uploads

[mguthrie]

We have some scheduled data uploads for our on premises data to upload to Qlik SaaS using the Qlik Data transfer tool. It works the first few times but we keep getting errors such as this: 

It seems like the temp files aren't being released? I really don't want to have to restart the server we run this on to release the file locks everytime this occurs.

Does anyone have any info on what could be causing the issues?
