Execution of the ASP page caused the Response Buffer to exceed its configured limit.
Ran into a ticket here at work that had a few people stumped. We were trying to export a report as an Excel file so the user could down load it. This error popped up and long story short I got a ticket to check it out.
I found the answer on ClearGlass.net. Here’s a quick summary of the solution:
Solution:
If you get the above error when you click on an attachment, the attachment is larger than IIS is configured to allow. Change the AspBufferingLimit setting in Metabase.xml to a larger size. The default value is 4194304, which is about 4 MB. Change this to whatever limit is reasonable for the types of files your users will be attaching.
This change does not require stopping IIS, but to make the Metabase.xml file write-able, you need to go to the IIS control panel, right click the server, select properties, and check off the box that says “allow changes to MetaBase configuration while IIS is running”.

Thanks foe this post. This saved me lot of effort and solved my problem.
