IIS 7.5 cannot upload single files over 10MB yet can upload multiple, far exceeding 40MB if they are less than 10MB each

Hi

Using IIS 7.5 on Win Server 2008 R2 and have issues uploading files over 10MB in size each.

I can upload any number of files in one go, totalling way over 30-40MB as long as all the files themselves are under 10MB

Any ideas, I'm at a loss as I've altered all the limits from the default 30MB to 500 (not that that should have even had an effect instopping them)

Regards, Neil

What is the log error indicate, termination due to timeout?
Do you have debugging in the script to get/trap errors?
Does the upload writes data to disk, or does it buffer it in memory until complete? Any anti-virus that might inopportunly lock the file ....?

The issue could also be caused by the sending side thinking the connection terminated and abandoning the connection.
Does your upload interface provide status to the client uploading? Check whether your upload has a restriction on the upload size.

Try to upload the larger file size on the LAN with the server eliminating possibly network related issue including connection resets.

So you've modified your app config as referenced in the articles below?  Just want to get an idea of what it is that you modified.

What is the upload functionality implemented in: C#, VB.NET, ASP, PHP, etc?

Can you post your web.config?

Thanks all for the pointers. Turned out it was a setting the 3rd party supplier had hard coded in their system which they said wasn't there.
