WARN: Failed to deleted temporary file used for part

mao-aavn

Hi there,
I saw pretty much of these WARN logs below, I guess it connects to the file upload feature (with Ivy.wf().documents() API).
I didn't face any issue with the feature. Any ideas to avoid/improve this ? Thanks.

mao-aavn It does not directly belong to the call Ivy.wf().documents(). I guess you have somewhere in your application a file upload. I would say this does not happen with the document upload for a case in the portal. But you may have implemented your own file uploads somewhere. I guess you don't close a stream correctly.

Thanks @Alexander Suter , I confirm that it has been fixed after improving the logic to close the file input stream from FilesUploadEvent files. (Primefaces file upload)
