  I am getting the below error in my SSRS report

  Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12031

  I have googled and find out that we have to change the file size limit on web config file.

  I have changed the httpRuntime on server. But still I am getting the error.

  maxRequestLength="512000"

  The report is giving 450,000 records and is of size around 70 MB.

  Any help?

  Thank You
