It appears ESRI has been retiring their old free geocoding services, such as the one at http://tasks.arcgisonline.com/ArcGIS/rest/services/Locators/TA_Streets_US/GeocodeServer, as described if you visit that URL in a browser. I've found them to be up one minute, down the next, more often the latter as time goes on in the past week.
Anyway, the new ones are still free for certain use cases (like 'enter an address, zoom to it' as described here - basically any use other than batch geocoding), so in my case, with no ArcGIS Online subscription, a simple change from the old URL to the new one made my app work again, no other modifications needed. The new URL is:
http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer
If you go to that URL in a browser, it seems like you can't use it, but that is just because the Services Directory is disabled. An actual query will work - like go to this URL in a browser, you receive the answer:
http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/find?text=380+New+York+Street%2C+Redlands%2C+CA+92373&f=pjson
And the help for the new service, like how to use your subscription to do batch geocoding, is here.
Here's an example of what I'm doing, in Silverlight - hope it helps!
search address string as typed by the user: "101 s webster st madison wi"
my code snippet similar to yours:
ESRI.ArcGIS.Client.Tasks.Locator locatorTask = new ESRI.ArcGIS.Client.Tasks.Locator
{
Url = locatorConfig.ArcGISLocator.RESTURL,
ProxyURL = locatorConfig.ArcGISLocator.ProxyURL,
Token = locatorConfig.ArcGISLocator.Token
};
locatorTask.AddressToLocationsCompleted += new EventHandler<ESRI.ArcGIS.Client.Tasks.AddressToLocationsEventArgs>(ArcGISLocator_GeocodeCompleted);
locatorTask.Failed += new EventHandler<TaskFailedEventArgs>(ArcGISLocator_GeocodeFailed);
AddressToLocationsParameters addressParams = new AddressToLocationsParameters();
ArcGISLocatorParams paramFields = locatorConfig.ArcGISLocator.ParameterFields;
if (!string.IsNullOrEmpty(paramFields.AddressField)) addressParams.Address.Add(paramFields.AddressField, address);
if (!string.IsNullOrEmpty(paramFields.CityField)) addressParams.Address.Add(paramFields.CityField, city);
if (!string.IsNullOrEmpty(paramFields.StateField)) addressParams.Address.Add(paramFields.StateField, state);
if (!string.IsNullOrEmpty(paramFields.ZipField)) addressParams.Address.Add(paramFields.ZipField, zipCode);
if (!string.IsNullOrEmpty(paramFields.CountryField)) addressParams.Address.Add(paramFields.CountryField, country);
locatorTask.AddressToLocationsAsync(addressParams);
the values of the locatorConfig properties you see in the snippet:
The values of variables you see near the end of the snippet, parsed out of that address string:
- address: "101 s webster st"
- city: "madison"
- state: "wi"
- zipCode: ""
- country: ""
And the request sent, grabbed from Fiddler:
GET http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/findAddressCandidates?Address=+101+s+webster+st&City=madison&State=wi&Zip=&Country=&f=json& HTTP/1.1
and the response JSON, by pasting that URL into a browser address bar:

You could check to see if its crashing or simplying trowing error in ArcGIS Server logs. If its crashing and creating the DMP files under C:\arcgisserver\logs\\errorreports path then open that DMP file with Visual Studio to see the error message.
This majorly due to AGS account access to your local machine AGS directory. As per ESRI below mention step can be used to resolve it, but its a general stpe -
To run this, on the ArcGIS for Server Machine simply Navigate to 'Start -> All Programs -> ArcGIS -> ArcGIS 10.x.x for Server -> Configure ArcGIS Server Account'. When prompted simply re-enter the password for the account list which runs your Server services.
You need to check you data source and access to that as well. Refer below mention link as well -
http://server.arcgis.com/en/server/latest/administer/linux/common-problems-and-solutions.htm
search for 001369 error and same you need to check in ArcGIS Server logs.
