WCF SingleTon问题 [英] WCF SingleTon Problem

问题描述

大家好，

我们需要在应用程序中拥有在线用户，

我使用InstanceContextMode = System.ServiceModel.InstanceContextMode.Single

每当用户登录和注销时，我都会保存他的姓名和回叫

在词典集合中，但是当用户数超过
时，我遇到了疯狂的问题
20，服务进入故障状态，

我将MaxConnection，maxConcurrentCalls，maxConcurrentSessions和maxConcurrentInstances设置为等于1000，

但这没有帮助.

请帮助我，

推荐答案

请在WCF中使用跟踪来解决您的问题.
从您的描述很难理解引擎盖下发生了什么.
作为一个问题，我想这可能是一些内存泄漏问题.

因此，在WCF中包括跟踪，并仔细检查吧！.

Please use tracing in WCF to rack your problem.
From your description is very hard to understand what happened under the hood.
As an issue i suppose it could be some memory leak problem.

So include tracing in your WCF , and look throuht it!.

<system.diagnostics>
		<sources>
			<source name="System.ServiceModel" switchvalue="Information, Critical, Error">
							propagateActivity="true">
				<listeners>
					<add name="log" />
				</listeners>
			</source>
			<source name="System.ServiceModel.MessageLoging" switchvalue="Critical">
				<listeners>
					<add name="log" />
				</listeners>
			</source>
		</sources>
		<sharedlisteners>
			<add name="log" type="System.Diagnostics.XmlWriterTraceListener">
			initializeData="Traces.svclog" />
		</add></sharedlisteners>
		<trace autoflush="true" />
	</system.diagnostics>

还有，您出于什么目的设置maxConcurrentInstances?我猜想，它应该只有一个...

And one more, for what purpose you set maxConcurrentInstances ?? As i suppose , it should be only one...
