System.IO.FileNotFoundException: Could not find file

[Steven]

We are receiving the following error and am wondering if you have any ideas what might be happening. We have 100's of files being uploaded daily and this occurs pretty rarely.

I am thinking it might have to do with  temporaryfileexpiration but I couldn't find what the default value is

thanks

Hello Steven,

 
The default value of the TemporaryFileExpiration property is set to four hours. Since you are uploading 100 of files every day it possible that it is not enough time for uploading the appropriate file. In this case I will recommend you to increase the temporatyFileExpiration value in order to provide more time for uploading.

Kind regards,
