Remarks

For example, this exception can be observed when a service attempts to perform an operation on a Service Fabric or FabricReplicator object while it is in the closed state. Another example is when an API is invoked on a FabricClient object when it is in the closed state.

Handling FabricObjectClosedException for FabricClient calls: If a FabricClient call sees FabricObjectClosedException, see FabricClient Exception Handling for handling common FabricClient failures.

Handling FabricObjectClosedException for Reliable Collections : 1. If the service sees FabricObjectClosedException in RunAsync, it should catch the exception and return from RunAsync. The CancellationToken passed to RunAsync would be signalled. All background tasks should complete execution when this cancellation is signalled. 2. If the service sees FabricObjectClosedException while processing a client request (e.g. via their communication listener), the service should throw the exception to the client to signal the client that it should re-resolve the service in order to locate the new Primary.

[NOTE] If an IReliableState was removed via IReliableStateManager.RemoveAsync(), any calls trying to access this IReliableState would see FabricObjectClosedException. These calls needs to be synchronized with the IReliableStateManager.RemoveAsync() call and should know that the IReliableState has been removed. Possible ways to handle this case are: 1. Recreate the IReliableState if it was removed and retry the operation. 2. Ignore the IReliableState and process other IReliableState in the service. 3. Use locks to avoid the race. Hence if a remove call comes in, the user can stop processing the IReliableState further.
