  Hi,

  I am executing a huge report in SSRS 2008, after some time the report doesn't renders and there is an error icon at the left bottom of the web page. When I click open it to see the details, it gives following error;

  Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while

  processing the request on the server. The status code returned from the server was: 12029.

  Any help on this will be appreciated.

  Regards.
