I have an interesting problem, we are working on sharepoint 2013 and sometimes, we have an unknown error with random PDF or PPTX or whatever you want;
When we want to upload this kind of file, upload get stuck for 30mn and give us an unknown error.
(translation: Sorry, for some reason this document couldn't upload. Try again later or contact your administrator. )
Btw our limitation is 2gb and the files that we upload : 3-8mb... Timeout in IIS is increased to 1200 (tried 120...)
I have no log... I'm a bit lost...
