On my web site my Crystal report viewer on "drill-down" reports is timing out after about 80 - 90 seconds.

Any ideas?

What viewer are you using?

Most viewers con't have a timeout but the connection to the database might.

VB Code attached
IIS Is set to 12,000 seconds timeout

These app keys are in the web.config
        <add key="CrystalImageCleaner-AutoStart" value="true"/>
        <add key="CrystalImageCleaner-Sleep" value="240000"/>
        <add key="CrystalImageCleaner-Age" value="240000"/>

This is the code for the viewer

HTML
<%@ Register Assembly="CrystalDecisions.Web, Version=12.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"
    Namespace="CrystalDecisions.Web" TagPrefix="CR" %>

<div>
        <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="true"
            ReportSourceID="CrystalReportSource1" ToolPanelWidth="1px" />
        <CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
        </CR:CrystalReportSource>
    </div>
Public Sub getReport()
        Try
            _rpt = Request.QueryString("rpt")
            _id = Request.QueryString("id")

            Dim objConn1 As New SqlConnection
            Dim oCom As New SqlCommand
            Dim dr As SqlDataReader

            objConn1.ConnectionString = System.Configuration.ConfigurationManager.AppSettings("ConnPortal")
            oCom.Connection = objConn1
            objConn1.Open()
            oCom.CommandText = "sp_portal_CrystalReportUserAccessGet"
            oCom.CommandType = CommandType.StoredProcedure
            oCom.Parameters.Add(New SqlParameter("@userName", SqlDbType.NVarChar)).Value = Session("userName")
            oCom.Parameters.Add(New SqlParameter("@reportId", SqlDbType.Int)).Value = _id
            dr = oCom.ExecuteReader

            If dr.Read Then
                If Session("userName") = dr("username") And _rpt = dr("reportName") Then
                    CrystalReportSource1.Report.FileName = "~/reportsCrystal/" & _rpt
                    lblError.Text = ""
                Else
                    lblError.Text = "Report access = 'NONE'"
                End If
            Else
                lblError.Text = "Report access = 'NONE'"
            End If
            objConn1.Close()
        Catch ex As Exception
            lblError.Text = ex.Message
        End Try
    End Sub

WHen are you getting the timeout?

When you first display the report or on drill-down?

It is after the report loads...and then sits without interraction for 60-80 seconds.

After that...when clicking on the report drill down it errors out

I don't know this for sure but a drill-down may use the postback and you may be losing the session variables like username and reportname

I was thinking that myself...but the session timeouts on the server are huge, as thery are in my Web.Config...and the ReportName is called in the Request.QueryString

Web.Config
<httpRuntime maxRequestLength="999999" executionTimeout="21000"/>
<sessionState timeout="180"/>
