C# – Reporting Services 2005 Timeout When Exporting via Web Service

We narrowed down the large PDF exports from SSRS and found 2 main culprits

1) Unless images are JPG or PNG colour type 3, they are expanded to BMP's See here

2) Unless you configure SSRS to behave otherwise (not recommended), then SSRS will embed fonts or font subsets into the PDF, unless they are one of the 5 'standard' PDF fonts.

Although none of the standard fonts (other than Symbol I guess) are installed on most Windows OS's out of the box, we've found that if you use Times New Roman, Courier New, or Arial then forward and reverse font substitution will take place.

The easiest way to convert your RDL's is to view them as XML and search and replace the FontFamily tags.

If you have to use a non standard font, then, you can still minimize the damage:

• Use as few fonts as you can. Search through the RDL XML to make sure there aren't any redundant fonts.
• Use TTF fonts if you use different sizes of the font.
• Try not to mix normal, bold and italic variants of the font, else it will be embedded multiple times.

Couple of options:

1) Modify SessionTimeout and SessionAccessTimeout system properties.

Here is a sample script for rs.exe which will set these values for you:

Public Sub Main()
    Dim props() as [Property]
    props = new [Property] () { new [Property](), new [Property]() }

    props(0).Name = "SessionTimeout"
    props(0).Value = timeout

    props(1).Name = "SessionAccessTimeout"
    props(1).Value = timeout

    rs.SetSystemProperties(props)
End Sub 

You can run this script with the following command:

rs -i sessionTimeout.rss -s http://localhost/reportserver -v timeout="6000"The timeout is expressed in seconds, so this example sets the SessionTimeout and SessionAccessTimeouts to about an hour and a half.

2) Change Report Execution Timeout via Report Manager Open Report Manager At the top of the page, click Site Settings. This opens the General Properties page of the site.

Report Execution Timeout Specify whether report processing times out after a certain number of seconds. (via http://msdn.microsoft.com/en-us/library/ms181194.aspx)

3) Set the HttpRuntime ExecutionTimeout

a. Open the ReportServer’s Web.config file by going to Start -> Administrative Tools -> Internet Information Services.

b. From there, expand Web Sites -> Default Web Site, and click on ReportServer. On the right-hand pane, right-click ‘Web.Config’ and select ‘Open’.

c. Locate the HttpRuntime parameter. If it doesn’t exist, you will have to create it within the section.

d. Set the executionTimeout value to ‘10800’ (3 hours) as shown below:

<system.web>
<httpRuntime executionTimeout = "10800" />
</system.web>

4) Increase the script timeout on the report server

1. Go onto your Reporting Server and open up Internet Information Services; right-click on the ReportServer and select Properties.
2. Go to the Options tab, and set the ASP Script timeout to 300 seconds (this didn't really work for me).

5) Set the report to never time out on the server

1. Open your web browser on the server and go to http://localhost/Reports
2. Navigate to the Report location and click on the problem report(s).
3. On the left-hand pane, click on Properties.
4. In the ‘Report Execution Timeout’ click the ‘Do not timeout report execution’. (via http://geekswithblogs.net/ssrs/archive/2009/10/30/steps-to-resolve-ssrs-timeout-issues.aspx)
