We are current users of DMX and have always fought the large uploads issue(s).  After looking through the many previous posts concerning large file uploads and downloads and trying all of the suggestions, we are still having trouble. 

Our web.config has this pertinent part.

We are running the latest update we have now lost the progress bar that we used to have.  I have run the Reinstall Config script from Admin -> Scripts and added the

c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll

to our Wildcard application map.

We have also changed the web.config to

per the install document.

Everytime we try to upload a document, we get:

A critical error has occurred.
Exception of type 'System.OutOfMemoryException' was thrown.

Is there anything else I am missing?  We can't get anything larger than about 300MB to upload.  We have need to upload ~ 1GB files at this point.  Also, how can we tell that it is actually using the Write to Disk feature instead of buffering to memory? 

Thanks,

Mike

The original post ate my web.config settings... sorry.  Here they are:

httpRuntime maxRequestLength="2048000" requestLengthDiskThreshold="2048000" executionTimeout="600" useFullyQualifiedRedirectUrl="false" /

and

trust level="High" originUrl=".*" /

Peter,

Thanks for responding! 

Yes, we are using the RadUploadModule, or at least I think we are? It is not showing up when a file is being uploaded.  The web.config shows it in the httpHandlers and the trust level is set to high for the site.  Below is the section from the config file

... XML stuff removed (Peter)

I guess, that's part of my question, how do we confirm that it is writing directly to disk?

ARRGGH...The post ate my html again. I must be doing something wrong...  Anyway, Open angles are replaced with ! and closed angles are replaced with ?
