奇怪的间歇WCF错误铸造IPermissions

Question

我目前正在试图解决我不能为我的生活工作的任何线索事业WCF服务错误...

问题本质上是它会得到一个InvalidCastException尝试将事件转换为IPrincipal对象（我在错误中看到的XmlDictionaryString & ClassDataContractCriticalHelper）。服务器端它甚至没有打我们的代码，问题是我们只是间歇性地得到这个问题（每周2-3次，每次使用API​​多次），并给出了流量的大小如果我们留下完整的信息日志记录，我们将在几分钟内完成生产服务器硬盘驱动器的服务。

堆栈跟踪为：

本来我们已经启用了邮件的安全性，给出的暗示的IPrincipal我们换到TransportWithMessageCredential和HTTPS加密只是为了看看它的工作，但它让我们无处。配置是：

<serviceHostingEnvironment> 
    <baseAddressPrefixFilters> 
    <add prefix="http://www.anonymized.com"/> 
    </baseAddressPrefixFilters> 
</serviceHostingEnvironment> 
<bindings> 
    <basicHttpBinding> 
    <binding name="httpBindingConfig"> 
     <security mode="TransportWithMessageCredential"> 
     <message clientCredentialType="UserName"/> 
     </security> 
    </binding> 
    </basicHttpBinding> 
</bindings> 
<services> 
    <service behaviorConfiguration="httpBindingBehaviour" name="Anonymized.Service.Implementation"> 
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="httpBindingConfig" name="httpBindingEndpoint" 
       contract="Anonymized.Service.Contract" /> 
    <host> 
     <baseAddresses> 
     <add baseAddress="http://localhost/Anonymized" /> 
     </baseAddresses> 
    </host> 
    </service> 
</services> 
<behaviors> 
    <serviceBehaviors> 
    <behavior name="httpBindingBehaviour"> 
     <serviceThrottling maxConcurrentCalls="160" maxConcurrentSessions="100" maxConcurrentInstances="100" /> 
     <dataContractSerializer maxItemsInObjectGraph="2147483647"/> 
     <serviceDebug includeExceptionDetailInFaults="true" /> 
     <serviceCredentials> 
     <userNameAuthentication userNamePasswordValidationMode="MembershipProvider" membershipProviderName="AnonymizedSqlMembershipProvider" /> 
     </serviceCredentials> 
     <serviceAuthorization principalPermissionMode="UseAspNetRoles" roleProviderName="SqlRoleProvider"> 
     </serviceAuthorization> 
    </behavior> 
    </serviceBehaviors> 
</behaviors> 

有没有人有任何理论，甚至暗示在哪里看？

这是那种问题DebugDiag是完美的。您可以配置崩溃规则以仅在发生此异常时记录故障转储。 DebugDiag附带的崩溃分析脚本可能会告诉您足够的信息，因此您可以解决您的问题。否则，您可能需要手动调试才能找到根本原因。
