调用服务WCF测试客户端失败

我有一个WCF服务。我对它有意见。
每当我从服务(使用WCF测试客户端)调用具有大响应数据(例如:GetUserByUsernameWithAllRelations())的方法时，会发生以下错误:

An error occurred while receiving the HTTP response to http://localhost:17497/SmartService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
Server stack trace:

但是，如果我调用一个方法与一个小的响应数据(例如:GetAllUsersCount())，它的工作没有任何问题。

p。S:
在我们公司，我们有一个代理在我们的窗口使用局域网和互联网。我禁用了它，但是没有任何改变。

WCF测试客户端错误:

Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.
