SSRS Report - Excel Export - Timed Out issue

Question

Hi All,
I have a report which has around 10k records. I am getting Timed out error sometimes when I try to export data to excel. But, strangely this happens most of the time. But, sometimes, i am able to download the excel. I have even tried download .csv..its works
fine (i just tried couple of times).. I have even tried setting the Do not timeout report execution = true and even tried the other option of increasing the report execution timeout.
Is there any other option in Configuration files that I need to make the changes?
Kindly help me.
Thanks,
Prawin

Hello everyone,
It seems that we have a similar problem. Our configuration:
Report server 2008 integrated in SharePoint 2007 on a windows server 2008..
We have a report that doesn't work when it has to return to much data (when the render time is to long). We get an error in Sharepoint saying 'Unexpected error' when I make a big selection. However, this doesn't happen when I use the same selection for this
report in the SSRS native mode. The report will render for a couple of minutes then but wil return a result.
Here is the reportserver log for when I execute the report from the Sharepoint integrated mode:
Report='/Financien/rsrapporten/budget.rdl', Stream=''

The report is set in Sharepoint to not give a timeout. I even increased the timeout in the web.config for the sharepoint farm.. Does anybody have any idea how to fix this?? BTW, I prefer not to let my users work with the report in native mode (this is a
workaround, it should work within Sharepoint!).
