The remote server returned an error: NotFound

[Esriguy]

In my sliver light application, I making call to custom Geo processing service to perform some heavy weight operations at server side.
This service call always returns an error "The remote server returned an error: NotFound." 

Below is pseudo code, Application always goes to "saveLine_Failed"

            Geoprocessor saveLineShotInfo = new Geoprocessor(url);
            saveLine.ExecuteCompleted += new EventHandler<GPExecuteCompleteEventArgs>(saveLine_ExecuteCompleted);
            saveLine.Failed += new EventHandler<TaskFailedEventArgs>(saveLine_Failed);
            saveLineShotInfo.ExecuteAsync(gparameters);

Error:

System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound.
   at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult)
   at System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClass5.<EndGetResponse>b__4(Object sendState)

   at System.Net.WebClient.GetWebResponse(WebRequest request, IAsyncResult result)
   at System.Net.WebClient.DownloadBitsResponseCallback(IAsyncResult result)}

I debugged using Fiddler and copied the response below.  Fiddler displays 500 error code.

I have increased "executionTimeout" in httpRuntime element in my web.config to 3600 seconds and also increased Geo processing service maximum time out parameter as well. But nothing works out. I could not find exact root cause for this issue.

Please help me on this immediately.

I would like to document this too but we don't have an actual repro case. Do you mind sending code snippets and/or steps to reproduce? I understand the same code works for less complex geometry. Have you tried using sample server GP? I wanted to check if this issue had been fixed in v2.4. Thank you for your patience. Alternatively, you can also submit bug report to tech support.

Jennifer:

Thank you. Please give some time do provide you the sample code snippet. I am very much looking for this fix.

Does Simplifying the geometry solves your problem?
