Issues that are fixed in this update

AppFabric Cache

Issue 1

The AppFabric Caching service crashes intermittently with the following exception:

{System.Runtime.CallbackException: Async Callback threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object.
at System.Runtime.AsyncResult.End[TAsyncResult](IAsyncResult result)

Issue 2

When you run the Stop-CacheHost AppFabric PowerShell command together with the -Graceful switch, you can't stop the cache host, and you receive the following error message:

Exception type: System.Collections.Generic.KeyNotFoundException
Message: The given key was not present in the dictionary.
InnerException: <none>

Issue 3

When you run the Register-CacheHost AppFabric PowerShell command, the command fails, and you receive the following error message:

Register-CacheHost : ErrorCode<PortAlreadyInUseError>:SubStatus<ES0001>:TCP port 22234 is already in use.


Note This failure generally occurs if the cache ports are bound to any IP address.

Issue 4

After you apply this cumulative update, AppFabric uses a nonblocking garbage collection (background server garbage collection). Nonblocking garbage collection is a new feature in the Microsoft .NET Framework 4.5. 

To enable this feature, follow these steps:

  1. Upgrade the servers to the .NET Framework 4.5.

  2. Install the cumulative update package.

  3. Enable the fix by using the following setting in the DistributedCacheService.exe.config file:

    <appSettings><add key="backgroundGC" value="true"/></appSettings>
  4. Restart the AppFabric Caching service for the update to take effect.

Note By default, the DistributedCacheService.exe.config file is located under the following directory:

%ProgramFiles%\AppFabric 1.1 for Windows Server

Known issues

When you uninstall any cumulative update for Microsoft AppFabric 1.1, you may see a dialog box that states "The feature you are trying to use is on a network resource that is unavailable." In this situation, the cumulative update will not be uninstalled. To work around this issue, follow these steps:

  1. Download Microsoft AppFabric 1.1 for Windows Server from here.

  2. Open the Command Prompt, and then run the .exe file together with the '/?' option. For example, run WindowServerAppFabricSetup_x86.exe /?.

  3. Leave the AppFabric 1.1 for Windows Server Setup Wizard dialog box that has many setup commands open when it appears.

  4. Use Windows Explorer to move to the root folder of the boot drive. You can see a newly created temporary folder that has a randomly generated name, such as "C:\ced4e5c208fd0a43edc4a195edfe47".

  5. Copy that temporary directory to a new location, such as to "c:\appfabrictempfiles".

  6. Close the AppFabric 1.1 for Windows Server Setup Wizard dialog box.

  7. When you now try to uninstall the cumulative update and are prompted for the location of the MSI, you can point it to the "packages" subfolder in the copy of the temporary directory that you created (such as to "c:\appfabrictempfiles\packages"), and the uninstallation should be successful.
