I encounter the program throw cannot access dispose object when deploy program at IIS in Window Server 2012.
according to the code, The code can be run normally in my PC Development and Production but there is problem when I deploy to test server the symptom is I can run program finely in the first time after deploy then when I re-enter the page it throws cannot access disposal object.
I also check the service using soap to send request repeatedly but the problem not found and now after testing in difference PC and server it can run as well.
I'm not sure what I have to do more about config or it about server spec. becuase the others that can run have ram more than 8GB but in test server that found the problem only has 4GB of ram or I have to edit my code?
code section that bind datasource to service
#region Employeeprofile
this.EmployeeProfileDataSource.DataMember = "GetWF_30EmployeeProfile";
this.EmployeeProfileDataSource.DataSource = typeof(THP.Welfare.Reporting.ReportManager.EmployeeProfilesReportManager);
this.EmployeeProfileDataSource.Name = "EmployeeProfileDataSource";
this.EmployeeProfileDataSource.Parameters.AddRange(new Telerik.Reporting.ObjectDataSourceParameter[] {
new Telerik.Reporting.ObjectDataSourceParameter("employeeNo", typeof(string), empNo)});
report.DataSource = this.EmployeeProfileDataSource;
#endregion
#region Spouse
this.SpouseDataSource.DataMember = "GetWF_30SummaryMarriageFromBeforeApprove";
this.SpouseDataSource.DataSource = typeof(THP.Welfare.Reporting.ReportManager.EmployeeProfilesReportManager);
this.SpouseDataSource.Name = "SpouseDataSource";
this.SpouseDataSource.Parameters.AddRange(new Telerik.Reporting.ObjectDataSourceParameter[] {
new Telerik.Reporting.ObjectDataSourceParameter("employeeNo", typeof(string), empNo)});
then EmployeeProfilesReportManager initiate service and call
public EmployeeProfilesReportManager()
{
_service =Autofac.Integration.Mvc.AutofacDependencyResolver.Current.GetService<IService.IReportEmployeeProfileService>();
_logExceptionService = Autofac.Integration.Mvc.AutofacDependencyResolver.Current.GetService<IService.ILogException>();
}
in service layer it implements IDisposable
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public class ReportEmployeeProfileService : IReportEmployeeProfileService, IDisposable, ICommunicationObject { }
and there are code handle Dispose
protected virtual void Dispose(bool disposing)
{
if (disposed){
return;
}
if (disposing)
{
handle.Dispose();
}
disposed = true;
}
public void Abort()
{
_dbContext.Database.Connection.Close();
_dbContext.Dispose();
Dispose(true);
}
public void Close()
{
_dbContext.Database.Connection.Close();
_dbContext.Dispose();
Dispose(true);
}
I expect the server that has problem can run normally like others server. thank you.
after using diagnostic tool I've got this message

after following the answer now I can solve the problem with edit my code as
#region Field
private readonly Owned<IService.IReportEmployeeProfileService> _service;
private readonly Owned<IService.ILogException> _logExceptionService;
#endregion
#region Constructor
public EmployeeProfilesReportManager()
{
_service = Autofac.Integration.Mvc.AutofacDependencyResolver.Current.GetService<Owned<IService.IReportEmployeeProfileService>>();
_logExceptionService = Autofac.Integration.Mvc.AutofacDependencyResolver.Current.GetService<Owned<IService.ILogException>>();
}
#endregion
and in all method that I call service like this
public List<SummaryMarriageInfoBeforeApproveModel> GetSummaryMarriageFromBeforeApprove(string employeeNo)
{
var result = _service.Value.GetSummaryMarriageFromBeforeApprove(employeeNo);
_service.Dispose();
_logExceptionService.Dispose();
return result;
}
Minor disclaimer: I know Autofac, but I've never used the Telerik reporting services engine. But I can guess what's happening.
It appears you have a threading/race condition going on.
In the comments, you noted [formatted for readability]:
in in startup.cs have create channel as singleton
builder.Register(c => new ChannelFactory<T>("DefaultService")).SingleInstance();
builder.Register(c => c.Resolve<ChannelFactory<T>>().CreateChannel()).UseWcfSafeRelease();
I assume the <T> is short for what you actually are using.
I also see this snippet:
public EmployeeProfilesReportManager()
{
_service =Autofac.Integration.Mvc.AutofacDependencyResolver.Current.GetService<IService.IReportEmployeeProfileService>();
_logExceptionService = Autofac.Integration.Mvc.AutofacDependencyResolver.Current.GetService<IService.ILogException>();
}
The report manager is using service location on the MVC dependency resolver to get some stuff. The important thing to note about the MVC dependency resolver is that it's tied to the current request. When the current request ends, the request lifetime scope is disposed along with all the disposable objects that got resolved in that scope. That includes things like WCF service clients.
Finally, the stack trace for the error that got posted, at the bottom, looks like:
Telerik.Reporting.Services.Engine.Rendering.RenderWithCulture(Telerik.Reporting.Services.Engine.ReportRendererArgs)
Telerik.Reporting.Services.Engine.Rendering.ThreadFunc(System.Object)
System.Threading.ExecutionContext.RunInternal(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)
System.Threading.ThreadHelper.ThreadStart(System.Object)
There's a ThreadStart call there, so this rendering engine thing appears to be running on a different thread, something that is potentially launched from a controller but maybe isn't tied to the request lifetime.
What I'm guessing happens is:
We see this a lot in Autofac where folks try to spin up background services or non-request-based things in web apps but still try to tie the background service threads to web/request-related dependency resolvers and lifetime scopes.
Given I don't know enough about the Telerik reporting engine, I don't know what hooks there are to allow DI into it. Honestly, I can't even guarantee this is the problem, but it looks exactly like these things that I've seen in other questions on here.
What I'd recommend:
CommonServiceLocator that also has the application container attached. Don't use the MVC dependency resolver in the EmployeeProfileReportManager or anything down that chain.IService.IReportEmployeeProfileService in your EmployeeProfileReportManager, resolve Owned<IService.IReportEmployeeProfileService>. The Owned<T> relationship in Autofac allows YOU to take control of disposal. This is important because the CommonServiceLocator resolves from the container and you'll get a memory leak if you don't take control of disposal yourself.EmployeeProfileReportManager make sure to dispose of the service client when you're done with it. Since you're using Owned<T> that won't automatically happen.
