Internet Explorer errors out while running a SSRS 2005 report for long time(more than an hour).
I have developed a report using SSRS 2005. This is embedded in a web application, which is built on C#/
ASP.Net (3.5 framework/VS 2008). The report is deployed in a report/db server, which is a part of two tier architecture ie. app and db. This report takes more than an hour for execution and producing the output, as it calls a stored procedure which processes large volume of data. When the report is being run and the elapsed time is close to an hour, then an error message is displayed as: "Internet Explorer can not display the webpage".Version of Internet explorer and IIS is 6.0. Event viewer log has following message: Event Type: Warning Event Source:
ASP.NET 2.0.50727.0 Event Category: Web Event Event ID: 1309 Date: 1/7/2013 Time: 10:58:04 AM User: N/A Computer: -------------------- Description: Event code: 3005 Event message: An unhandled exception has occurred.

I'd seriously start work on reducing the time that the procedure takes to execute. If it cant be reduced significantly then I'd recommend running it on a schedule (every day, twice a day, ever 3 hours ????) and have the results in a table that the SSRS report references. This way noone opening the report will accidentally start the procedure - potentially an unlimited number of times.
