WCF / ASMX :: IIS Memory Increasing For Each Client Request In Asmx Web Service?
Nov 8, 2010
A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
I have a webservice which works 100% fine on my developer machine. Where Web Service is installed on LOCALHOST on my developer machine,Then i went to my servers, I installed webservice on one server and map it with the server where the website is hosted, Then i tried accessing this service using BROWSER from my web server, it worked fine, That means the mapping was done perfect.Then i run my program on web server (website). It worked fine on page1, then on page2, but when i did the same and call same function on page3, It popped me any error of
Calculator CALC = new Calculator(); int a = CALC.Add("23","27"); and result will be stored in a;
Please help me to encrypt this request using the X509 certificate. Am having a certificate with public key and with subject "My Calculator"and also decrypt the result with the private key "abcdef" and with subject "My Response"
I've got a web service on a server with valid IP and valid DNS entries. I'm using an asynchronous thread in a WPF .NET application to access methods from that web service. Under normal connection conditions, for almost all users, the connection and method works fine. Under a very specific condition - Verizon Aircard being used to connect, no VPN connection to the company through SSTP, on a PC with Forefront Client Security installed - the web service will return a "HTTP Error 400: Bad Request" error to the user. If the same user on the same PC connect their VPN connection, the method works flawlessly.
for the past couple of days i am facing an issue where the first call from my ASP.NET 4 application (VS 2010 Web Site) hosted in IIS 7 to an XML web service is dead-slow. subsequent calls are fast until the AppDomain is restarted.
I have tried all solutions related to pre-generating the serializer assembly but nothing worked. Anyway THEN I was sure it is an IIS-only issue because if i consume the xml web service from a console .net application then all the calls are fast. its even fast from an ASP.NET web site NOT hosted in IIS instead running on the development server. SO clearly the problem is there only when my app is hosted in IIS.
We currently have the code in WCF to sign the outgoing client requests' SOAP Body, however we need the same code for use with WSE 3.0. I can't find any examples of this.

I am working with WCF REST Service Application in .Net 4.0 and my service is hosted on II7 (Windows 7 Ultimate - 64 bit).My service and all other code is working completely fine.But when I use the '&' character in request url, it shows the following Error.I have already tried adding following section in my web.config as shown here on www.asp.net
when client call my web service, i read owner cookie?
For example : When Guest browse www.abc.com, i write a cookie that its name BrowseTime. www.xyz.com using web service on www.abc.com . Can I get abc.com's BrowseTime cookie when xyz.com call WebService? Or alternative solution like (third part cookie or any)
I am trying to call webservice from my web application. The web application had integrated windows authentication. I've written custome principal class to do authorization. But when I give call to my web service with default credentials it gives me 'the request failed with http status 401 unauthorized.' error.
When I give call to my local webservice it is running fine (It also has integrated windows authentication) But when I add reference of same web service from QA server I am getting this error. Not sure what is happening. I also tried
I am getting following error in the Test which is in the same Box but IIS requires Https to view the Page. I have change Web.Config to accept https. I was able to add the Service References without any problem but while call the method I get The HTTP request was forbidden with client authentication scheme 'Anonymous'. this error message. I am trying to use userNameAuthentication.
I am having a strange issue in my C# Console Application:
Name Space: WcfConsoleApp Main Class: Program.cs Name Space: WcfConsoleApp.ServiceReference this namespace contains the WCF service reference
After building the project, the Program.exe avaliable in Debug folder is executing fine as expected.But when i move the exe to Client, where i need to actually run this exe, it works fine up to the line where i am referencing the Service, the line is:
WcfConsoleApp.ServiceReference.ServiceClient service = new WcfConsoleApp.ServiceReference.ServiceClient();
the consoel app crashes on the client machine at this line. (i know this because before this line, i display some mesage on the console)the same .exe and works fine at my development machine.I am sure it has to do some thing with reference path, i think the program is not getting to the path where service reference is avaliable. I have copied the full project folder as it is to the client, but still its is not working.
I have consumed an external webservice in my client application using WCF. And every thing works great in my Dev box(XP with IIS5.1)But when the same application is moved to Prod server(Win Server 2003 with IIS6.0) it fails. Below is the exception caught:
There was no endpoint listening at http://MyExternalWebServiceUrlWithSessionId could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.And the InnerException is: Unable to connect to the remote server.My Config file has the below settings:
While trying to access the service without specifing the user credentials everything work's ok and the current user(Thread.CurrentPrincipal.Identity.Name) at service is the logged in user.
When I try to set user credentials this way:
[Code]....
The service just ignores them.
When I try it this way:
[Code]....
I'm getting this error: "The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'."
I am consuming the java web service in .net client, when i sent a request to that web service, i am getting one exception in response object.It says "Client found response content type of 'text/plain', but expected 'text/xml'", along with this message i am getting the response in that exception.
I receive the following error, when trying to consume Wcf service:
"An existing connection was forcibly closed by the remote host". Consuming the service works fine when the host and the client are on the same machine. When I move the client to Hyper-V virtual machine (I didn't try it on a real computer) - it throws the error. Both firewalls are turned off Do you know what can cause such behaviour? Here are the details:
Both the client (hyper-v) and the service are on Windows server 2008 R2
Service url - http://wcftest/CalculatorService.svc (wcftest is the website and is mapped in the hosts file to localhost)
Service config:
[Code]....
Client config:
[Code]....
Are there any configuration settings which I'm missing?
I am working on WCF Data service which imported stored procedure, as below.
[WebGet] public List<GetMTSearchResultTest_Result> GettMTSearchResultTest() { MediaMarketResearch_PRODEntities ent = new MediaMarketResearch_PRODEntities(); return ent.GetMTSearchResultTest().ToList(); }
when i consuming this in my client application it says error as "The closed type MMRClient.MMRServiceReference.GetMTSearchResultTest_Result does not have a corresponding element settable property." I am getting this error while bind to the grid view as below.
DataServiceContext context = new DataServiceContext(new [URL])); IEnumerable<GetMTSearchResultTest_Result> empResult = context.Execute<GetMTSearchResultTest_Result>(new Uri [URL];
I was wondering if anything special is required to add a .NET web services to the "Services" tab in NetBeans to allow my java app to consume a .NET web service. I go and add my WSDL (simple method, 1 operation, takes a string), and I continuously get a NullReferenceError as below:
java.lang.NullPointerException at org.netbeans.modules.websvc.saas.model.wsdl.impl.WsdlModel.getServices(WsdlModel.java:65) at org.netbeans.modules.websvc.saas.wsdl.websvcmgr.WebServiceManager.addWebService(WebServiceManager.java:142) at org.netbeans.modules.websvc.saas.wsdl.websvcmgr.WsdlDataManagerImpl$1.run(WsdlDataManagerImpl.java:79) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1418) [catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:1957)
Is this something common? I'm using Netbeans 6.9.1 and yes, the webservice is a stub that takes a string and displays a static message right now.
I have a silverlight application that uses WCF service and i need to provide windows authentication using wcf.In order to achieve this i am trying to retrieve the client's credentials (windows credentials)inside wcf.
