I've got a web application running on Windows Server 2008 R2 and it uses the Crystal Reports 11.5 components to print a CR report to a printer. This is all working fine but after about an hours I get the following exception: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception. When I recycle the application pool the error disappears and it will work for a an hour more before failing again. I'm preventing this error from occurring by recycling every 15 minutes but this isn't ideal.
IIS Application pool settings: .NET 4.5 ASP.NET web application .NET Framework version is set to v4.0 Managed Pipeline Mode: Integrated Enable 32-bits application: True Identity is set to an AD user with full rights on the server
Build my project as x86. Installed CrystalReports_XI_R2_SP4_DeploymentPack on the deployment server.
Why is the exception occurring after an hour and how can I solve it?
