A ".temp" file is created when using Play! framework to upload a file

Dear all,

I am using Play! 2.6 and my application supports a user to upload a (potentially large) file. Sometimes, the file is not uploaded correctly in the sense that only part of it has been uploaded, meanwhile, a new .temp file is created together with the partially-uploaded file in the same directory (which the code does not do). Feels like there is some kind of “race” condition happening. And this is really hard to debug since I cannot re-create this repeatedly - most of the time, the upload just works fine.

Has anyone seen this before? what could be the problem behind this?

Many thanks!

thanks! let me check on this document.
