Hi, DNN 4.9.4 and DMX 5.2.1 running on Windows 2003 R2 and IIS6. When I try to upload a large file around 600 MB, the radupload control completes it's progress bar and then I get the following error: AssemblyVersion: 04.09.04 PortalID: 0 PortalName: Canterbury Documents UserID: 1 UserName: phost ActiveTabID: 38 ActiveTabName: Home RawURL: /Home/tabid/38/Default.aspx?Command=Core_Edit&CollectionId=684&RadUrid=07a12e3c-1363-4e04-8dde-13b2986f038c AbsoluteURL: /Default.aspx AbsoluteURLReferrer: http://pauldoc.canterbury...amp;CollectionId=684 UserAgent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.2; OfficeLiveConnector.1.3; OfficeLivePatch.0.0; FDM) DefaultDataProvider: DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider ExceptionGUID: c72cbd84-c184-492d-a2f2-a30ea20bbb61 InnerException: Exception of type 'System.OutOfMemoryException' was thrown.

I then get the error and the file is deleted. A smaller file (400MB) works fine and when the upload is complete, the file is moved from the Temp directory to the Upload directory and the UI goes to the next screen.

Hi Pauk, I believe the Lucene indexer loads the document into memory or the RadUpload does so while shifting it. I'm pretty confident DMX itself does not. We continue to work on out of memory errors and trap them where we can, but debugging 3rd party code is hard. We'll make a note and see if we can reproduce. In the meantime it looks like you're going to have to give the app pool more memory to deal with those files. Peter

About Bring2mind

Bring2mind is the company of Peter Donker, a DotNetNuke enthusiast who has been involved with the platform from the very beginning. At the same time as the market for modules emerged, he realized there was no good document management solution for the platform yet and he set about creating this. In part he based the module on his experience with other document management systems he used while working as a researcher. His module, Document Exchange, was an instant success and has since become the premier document management solution for DotNetNuke. In 2004 he created Bring2mind as a vehicle for the module and is one of the few successful businesses solely based on a DotNetNuke product.
