SYMPTOMS

Consider the following scenario:
  • You run a multithread Microsoft .NET Framework 4-based application that has high throughput.
  • The application calls the System.ComponentModel.TypeDescriptor.GetProvider method.
In this scenario, a System.InvalidOperationException exception occurs, and you receive the following error message:
Hashtable insert failed. Load factor too high. The most common cause is multiple threads writing to the Hashtable simultaneously.

For example, you run an ASP.NET application or a web service, and the application or the web service calls the System.ComponentModel.TypeDescriptor.GetProvider method.

Note When this issue occurs, the call stack resembles the following: 
at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add)
at System.ComponentModel.TypeDescriptor.NodeFor(Type type, Boolean createDelegator)
at System.ComponentModel.TypeDescriptor.GetProvider(Type type)
at System.ComponentModel.DataAnnotations.AssociatedMetadataTypeTypeDescriptionProvider..ctor(Type type)
at System.Web.Mvc.ModelBinderDictionary.GetBinder(Type modelType, IModelBinder fallbackBinder)
at System.Web.Mvc.ControllerActionInvoker.GetParameterValue(ControllerContext controllerContext, ParameterDescriptor parameterDescriptor)
at System.Web.Mvc.ControllerActionInvoker.GetParameterValues(ControllerContext controllerContext, ActionDescriptor actionDescriptor)
at System.Web.Mvc.ControllerActionInvoker.InvokeAction(ControllerContext controllerContext, String actionName)
at System.Web.Mvc.Controller.ExecuteCore()
at System.Web.Mvc.ControllerBase.Execute(RequestContext requestContext)
at System.Web.Mvc.MvcHandler.<>c__DisplayClass6.<>c__DisplayClassb.<BeginProcessRequest>b__5()
at System.Web.Mvc.Async.AsyncResultWrapper.<>c__DisplayClass1.<MakeVoidDelegate>b__0()
at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

CAUSE

This issue occurs because an internal HashTable object is accessed by multiple writers of the multithread application.
