Azure service fabric does not cancel with lots of tasks

I'm trying to test out various performance aspects of Azure Service Fabric to understand how it all works and have hit against some problems when cancelling a service.

In one particular test, I create 101 tasks, 50 reading a queue, 50 writing a queue and 1 showing progress and reporting it.

When the service gets stopped, for example just re-deploying the application I can see the cancellation token gets the request and some tasks cancel, but I see a lot of events in the event viewer basically saying

AsyncCalloutAdapter-22542743: end delegate threw an exception
   System.OperationCanceledException: Operation canceled. --->     System.Runtime.InteropServices.COMException: Operation aborted (Exception from   HRESULT: 0x80004004 (E_ABORT))
   at System.Fabric.Interop.NativeRuntime.IFabricStateReplicator2.EndReplicate(IFabricAsyncOperationContext context)
   at System.Fabric.Interop.AsyncCallOutAdapter2`1.Finish(IFabricAsyncOperationContext context, Boolean expectedCompletedSynchronously)
   --- End of inner exception stack trace ---

The only way to get this back is to either reset the local cluster.

When using a fewer number of tasks it all seems to work ok.

This is all using a local development cluster.
