C# 控制流异常

我在服务器应用程序中遇到以下异常。问题的原因可能是什么？如何调试问题。我从线程的不同点得到异常

ICC_SequenceService_SequenceReportService.NotifyEventRecived]-Exception Occured :The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it has been Aborted.-

这可能是因为当通道出现故障时，您的客户端不会中止通道，而是尝试关闭通道。不幸的是，如果您使用的是由wsdl.exe生成的客户端代理和using语句，那么这就是默认行为
