Azure-sdk-for-net: The operation was canceled

[ocengiz0]

Describe the bug
I often get this error even I updated the nuget package to latest
(regarding similar issue -> https://github.com/Azure/azure-service-bus-dotnet/issues/639)

Exception or Stack Trace

@kurtzeborn In this case, it would be @jsquire and @AlexGhiondea :)

[ocengiz0]

Any update @jsquire and @AlexGhiondea ?

[AlexGhiondea]

@ocengiz0 from looking at the callstack there isn't sufficient information to try and figure out the root cause. Would you happen to have a repro that we can look at?

[ocengiz0]

The only way I can reproduce is that while in a long debug session, I receive this error in my ExceptionReceivedEvent method in which implemented to MessageHandlerOptions
_subscriptionClient is ISubscriptionClient

```cs
var messageHandlerOptions = new MessageHandlerOptions(ExceptionReceivedHandler)
{
MaxConcurrentCalls = 1,
AutoComplete = false
};
_subscriptionClient.RegisterMessageHandler(ProcessMessagesAsync, messageHandlerOptions);

private Task ExceptionReceivedHandler(ExceptionReceivedEventArgs exceptionReceivedEventArgs)
{
var context = exceptionReceivedEventArgs.ExceptionReceivedContext;
var exception = exceptionReceivedEventArgs.Exception;
_logger.LogError(exception, $"Message handler encountered an exception: {exception.Message}, Endpoint: {context.Endpoint}, Entity Path: {context.EntityPath}, Executing Action: {context.Action}");
return Task.CompletedTask;
}

We are getting this exception too in our production. However its difficult to repro locally

                messages = await eventHubReceiver.ReceiveAsync(64);

[dwaijam]

Our callstack is
System.OperationCanceledException: The operation was canceled. at Microsoft.Azure.Amqp.AsyncResult.EndTAsyncResult at Microsoft.Azure.Amqp.ReceivingAmqpLink.EndReceiveMessages(IAsyncResult result, IEnumerable1& messages) at System.Threading.Tasks.TaskFactory1.FromAsyncCoreLogic(IAsyncResult iar, Func2 endFunction, Action1 endAction, Task`1 promise, Boolean requiresSynchronization) --- End of stack trace from previous location where exception was thrown --- at Microsoft.Azure.EventHubs.Amqp.AmqpPartitionReceiver.OnReceiveAsync(Int32 maxMessageCount, TimeSpan waitTime) at Microsoft.Azure.EventHubs.Amqp.AmqpPartitionReceiver.OnReceiveAsync(Int32 maxMessageCount, TimeSpan waitTime) at Microsoft.Azure.EventHubs.PartitionReceiver.ReceiveAsync(Int32 maxMessageCount, TimeSpan waitTime)

Hello, any update?
@nemakam, @binzywu, @kurtzeborn @jsquire and @AlexGhiondea

[nemakam]

I started a long running instance which captures the state when we run into this issue. Waiting for the bug to reproduce..

[Vikhyat08]

@ocengiz0 I a getting a similar issue #9543
I get into this state when message processing is taking a long time. I am getting Task canceled and service bus timeout exception. And getting these exceptions in bulk. How to handle these exceptions ?

[Marusyk]

I have the same #16975
