C# WCF SOAP服务方法无原因超时

我有一个带有wsHttpBinding的WCFSOAP服务，我有两个方法，第一个执行得很好，但由于某种原因，对第二个方法的调用超时。我调试了这个方法，代码中的一切都很好，它执行并返回，但是在客户端，在同一台机器上，请求超时。我创建了一个新的WCF服务应用程序项目，将整个代码+配置复制到新项目中，然后运行它，该方法有几次没有超时，然后突然又开始执行

以下是配置：

<system.serviceModel>
    <services>
      <service behaviorConfiguration="PolicyServiceBehavior" name="IST.Broker.Services.PolicyServiceV2.PolicyService">
        <endpoint address="" binding="wsHttpBinding" bindingConfiguration="PolicyServiceBindingConfiguration"
          contract="IST.Broker.Services.PolicyServiceV2.IPolicyService" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:63915/" />
          </baseAddresses>
          <timeouts closeTimeout="00:01:00" openTimeout="00:01:00" />
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="PolicyServiceBehavior">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <serviceThrottling maxConcurrentCalls="2147483647" maxConcurrentSessions="2147483647" maxConcurrentInstances="2147483647" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <wsHttpBinding>
        <binding name="PolicyServiceBindingConfiguration"
                 bypassProxyOnLocal="false"
                 transactionFlow="false"
                 hostNameComparisonMode="StrongWildcard"
                 maxBufferPoolSize="2000000"
                 maxReceivedMessageSize="2000000"
                 messageEncoding="Text"
                 textEncoding="utf-8"
                 useDefaultWebProxy="true"
                 allowCookies="true">
          <readerQuotas
                maxDepth="2000000"
                maxStringContentLength="2000000"
                maxArrayLength="2000000"
                maxBytesPerRead="2000000"
                maxNameTableCharCount="2000000" />
          <reliableSession
                enabled="true"
                inactivityTimeout="00:01:00" />
          <security mode="None"/>
        </binding>
      </wsHttpBinding>
    </bindings>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <directoryBrowse enabled="true"/>
  </system.webServer>

和执行：

[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerSession)]
    public class PolicyService : IPolicyService
    {
        private Employee _currentEmployee;

        public GetPolicyResponse GetPolicy(GetPolicyRequest request)
        {
            return new GetPolicyResponse(PolicyManager.GetPolicy(request.Id, request.PolicyNumber));
        }

        public void Initialize(int employeeId)
        {
            if (!InsuranceCompaniesServiceManager.IsInitialized)
            {
                var appPhysicalPath = HostingEnvironment.ApplicationPhysicalPath;
                _currentEmployee = EmployeeManager.GetEmployee(employeeId);
                InsuranceCompaniesServiceManager.Initialize(_currentEmployee, appPhysicalPath);
            }
        }

        public CreateMtplApplicationResponse CreateMtplApplication(CreateMtplApplicationRequest request)
        {
            return new CreateMtplApplicationResponse(PolicyManager.CreateMtplApplication(request.CompanyId, request.Policy.ToBusinessObject(), request.Vehicle.ToBusinessObject(),
                request.Clients.Select(x => x.ToBusinessObject()).ToList(), request.GreenCard.ToBusinessObject(), request.Sticker.ToBusinessObject()));
        }

        public void SignOut()
        {
        }
    }

该方法正在调用内部正在调用另一个服务的DLL。

请在第行下方注释，因为它将在配置代理时自动添加

<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

若您想检查，右键单击您添加服务代理的服务代理，选择“配置服务引用”，您会注意到/mex最后添加到服务的URL中

<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
