I have the max file size set to large (500Mb). When trying to upload a large file of about 30Mb (from chrome) it keeps uploading to app. 40% and then starts again. It ends with the message server not responding and the log: Dec 20 12:27:40 127.0.0.1 radiuzt: WARNING - Connector: Downloading file without known filename, presenting ObjectStoreId as name: 22407 Dec 20 12:27:40 127.0.0.1 radiuzt: ERROR - Connector: The file '22407' could not be found. How can I fix this?
