title: exporting an SSRS report to Excel failure
body: <p>When trying to export an SSRS report to excel, I am getting a runtime error.  I have looked at the logs and see the following:
  ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ReportServerStorageException: , An error occurred within the report server database.  This may be due to a connection failure, timeout or low disk condition within the database.;</p>
  
  <p>The report displays fine in Report Manager, and has run successfully in the past.  </p>
  
  <p>The report is only not very complex, and is approx 40 columns wide.  When I run the query in SSMS I get 27,628 records, and it takes 3 seconds to run (again, im SSMS).  The report runs fairly quickly in Report Manager also, and exporting the results to .scv format works as expected.  </p>
  
  <p>If any additional information is needed to help with resolving this, please let me know and I will provide it.  Thanks for you help in advance!</p>
  
  <p>Additionally, report has been set to not timeout. Report runs in VS2010 and exports to Excel as expected.</p>
