AppFabric 自动启动WCF - 服务器重新启动异常

Question

我的服务器设置是 Windows Server R2、IIS 7.5、AppFabric

我已将 WCF 服务启用为自动启动。

当服务器在夜间重新启动时，服务会失败并在事件日志中显示以下错误。

    WebHost failed to process a request.
 Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/12036987
 Exception: System.ServiceModel.ServiceActivationException: The service '/Host/emailservice.svc' cannot be activated due to an exception during compilation.

看起来 AppFabric 不处理线程，有人有类似的问题或解决方法吗？
