Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the

Hi,

I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,

"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029." 

I have no clue what it is up to. Please help me on this.

The other relatively smaller reports are coming up successfully without any issue.

I am using SQL Server 2008 R2 64 bit ent. edition and the OS is Win Server 2003 64 bit SP 2.

Regards.

I have written a web application that allows user to view crystal reports. When they select the report, application shows the parameters and when they enter parameters and click on OK, it processes the report and displays it on screen. My problem is, I added the AJAX Update panel with Updateprogress control. Now when users enter the parameters and click on Ok, it runs sometimes and then suddenly gives the following message:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

I have triple checked my project to make sure there are no Response.Write / server.tranfer commands. What I have is a label control and it displays any error in the try catch block. Now when I have the AJAX controls, if there is an error it does not even display the error on the label. It either refreshes the screen or show the above error. I googled and could not find a proper solution for this. Only option is to remove the AJAX control. I use VS2005.

The problem is when I run the same report 20 times, 2 or 3 times I get the above error.

 

Any help is greatly appreciated.

I have a server button in an aspx page. On click of the button I am opening a new aspx page as follows:Protected Sub btnView_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnView.ClickDim script As String = "OnLoadComplete();window.open('ViewReport.aspx?id=" & requestId & "','mywindow','width=1000,height=675,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,copyhistory=no,resizable=yes,left=10,top=10');"ScriptManager.RegisterClientScriptBlock(Me, Me.GetType(), "script1", script, True)       End Sub Sometimes not frequently when I click the button, I get an alert box with message as follows:Sys.Webforms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was : 500Please let me know why I am getting this error randomly and what is the solution to this.I guess there is some configuration issue as on one machine I am getting error, on other its working fine.ThanksVikas
