I have a monorail application using Windsor in production and have noticed a persistent memory issue in our w3wp.exe process for the application.
I have reviewed the following posts: http://groups.google.com/group/castle-project-users/browse_thread/thread/bc09194c70e3cecf/f1d874adfc72bdc0?lnk=gst&q=%22memory+leak%22#f1d874adfc72bdc0 http://groups.google.com/group/castle-project-users/browse_thread/thread/a14320c323be7cd0/79e16c568c6996db?lnk=gst&q=%22memory+leak%22#79e16c568c6996db http://groups.google.com/group/castle-project-users/browse_thread/thread/fff0e03ac2376a6/2d17ed6ee64f9780?lnk=gst&q=%22memory+leak%22#2d17ed6ee64f9780 and found they were either unrelated or their fixes were ineffective. The service does not have a high load but is usually up 24/7. The memory usage does not drop over the weekend (when usage drops to almost 0) so I don’t think it is session related. Over the course of several days/weeks, it is easy for the memory usage to grow to the single digit gigabytes. I have been using a Selenium script to "stress" the application using the following process: Go to the log in page. Log in. Open a dialog using ajax. Click a link to navigate to a new page. Log out. It then loops over this 200 times. >From the memory usage, it is clear when garbage collection happens, but the memory usage after each garbage collection rises over time. The dialog has a view component that inherits from the smart grid component. There are numerous simple view components on all of the screens. The system uses SOA for almost all data access, so there is no nHibernate or other ORM at this layer. I've tried NoTrackingReleasePolicy, just to see if that was the issue, as well as setting the life style for controllers/views to PerWebRequest instead of the MonorailFacility default of Transient (although the facility might be overriding this, I'm not sure). Below is a listing of all code related to the Windsor contain in our system: public class GlobalApplication : HttpApplication, IContainerAccessor, IMonoRailConfigurationEvents, IMonoRailContainerEvents { private static WindsorContainer container; … protected void Application_Start(object sender, EventArgs e) { container = new WindsorContainer(); container.AddFacility("mr", new MonoRailFacility()); //This was added for testing purposes container.Kernel.ReleasePolicy = new NoTrackingReleasePolicy(); container = WebComponentBuilder.AddRegistrationsTo(container); container = TranslatorsBuilder.AddRegistrationsTo(container); … } public IWindsorContainer Container { get { return container; } } public void Configure(IMonoRailConfiguration configuration) { // Configuring ViewEngine configuration.ViewEngineConfig.ViewPathRoot = Path.Combine (AppDomain.CurrentDomain.BaseDirectory, "Views"); configuration.ViewEngineConfig.ViewEngines.Add(new ViewEngineInfo(typeof (NVelocityViewEngine), false)); // Configure JQuery configuration.JSGeneratorConfiguration.AddLibrary("jquery-1.2.6", typeof (JQueryGenerator)).AddExtension(typeof(CommonJSExtension)) .ElementGenerator.AddExtension(typeof (JQueryElementGenerator)).Done.BrowserValidatorIs(typeof (JQueryValidator)).SetAsDefault(); } public void Created(IMonoRailContainer monorailContainer) { } public void Initialized(IMonoRailContainer monorailContainer) { IAjaxProxyGenerator ajaxProxyGenerator = new JQueryAjaxProxyGenerator(); monorailContainer.ServiceInitializer.Initialize(ajaxProxyGenerator, monorailContainer); monorailContainer.AjaxProxyGenerator = ajaxProxyGenerator; } } public class WebComponentBuilder { public static WindsorContainer AddRegistrationsTo(WindsorContainer container) { //Auto register all controllers and view components //Configure(reg => reg.LifeStyle.PerWebRequest) added for testing only container.Register(AllTypes.FromAssembly(typeof (HomeController).Assembly).BasedOn<SmartDispatcherController>().Configure (reg => reg.LifeStyle.PerWebRequest)); container.Register(AllTypes.FromAssembly(typeof (GlobalApplication).Assembly).BasedOn<ViewComponent>().Configure(reg => reg.Named(reg.ServiceType.Name).LifeStyle.PerWebRequest)); return container; } } public static WindsorContainer AddRegistrationsTo(WindsorContainer container) { container.Register(Component.For<ITranslate<ApplicationDto, ApplicationData>> ().ImplementedBy<ApplicationDtoToApplicationDataTranslator>().Named ("applicationDtoToApplicationDataTranslator")); return container; } Web.Config (I took a lot out that didn't look relevant) <?xml version="1.0"?> <configuration> <configSections> <section name="monorail" type="Castle.MonoRail.Framework.Configuration.MonoRailSectionHandler, Castle.MonoRail.Framework"/> <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/> <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="Everywhere"/> <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/> <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/> <section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/> </sectionGroup> </sectionGroup> </sectionGroup> </configSections> <!-- For more on MonoRail configuration see http://www.castleproject.org/monorail/documentation/v1rc3/index.html --> <monorail smtpHost="yoursmtphost" useWindsorIntegration="true"> <controllers> <assembly>Everest.Web</assembly> <assembly>Castle.MonoRail.ViewComponents</assembly> </controllers> </monorail> <system.web> <httpHandlers> <add verb="*" path="*.mr" type="Castle.MonoRail.Framework.MonoRailHttpHandlerFactory, Castle.MonoRail.Framework"/> <!-- block direct user access to template files --> <add verb="*" path="*.vm" type="System.Web.HttpForbiddenHandler"/> <add verb="*" path="*.njs" type="System.Web.HttpForbiddenHandler"/> <add verb="*" path="*.brail" type="System.Web.HttpForbiddenHandler"/ > <add verb="*" path="*.brailjs" type="System.Web.HttpForbiddenHandler"/> <add verb="*" path="*.st" type="System.Web.HttpForbiddenHandler"/> <add verb="*" path="*.xml" type="System.Web.HttpForbiddenHandler"/> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add verb="GET,HEAD" path="ScriptResource.axd" validate="false" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> </httpHandlers> </configuration> I have some graphs of the memory usage, but it doesn't look like I can post those here. If they would help, let me know and I can send them along (they all look like a saw blade with the valleys trending ever upwards). I can’t say for sure that it is Monorail/Windsor related, but I’m not sure what else it could be. We noticed the issue in an older version of these frameworks, but just upgraded them to the latest version: Castle.Monorail.Framework.dll - 2.1.0.100 Castle.Windsor.dll - 2.5.3.0 Castle.Core.dll - 2.5.2.0 Castle.DynamicProxy2.dll - 2.1.0.5642 Any help or direction would be greatly appreciated.
