NServiceBus.AmazonSQS 5.4 minor release available

Hi everyone,

We’ve just released NServiceBus.AmazonSQS 5.4.

Fixed bugs

  • #998 Use a rate limiter and in-memory cache to fix rate exceeded exception when using pub/sub compatibility mode

How to know if you are affected

You are affected if BOTH of these conditions apply:

  • Running SQS endpoints in publish-subscribe compatibility mode.
  • These endpoints publish (continuously or in bursts) events at a high throughput rate i.e. 30 or more unique event types per second.


Message processing fails and the following exception appears in the log:

exceptionType: "Amazon.SimpleNotificationService.AmazonSimpleNotificationServiceException",
exceptionMessage: "Rate exceeded", stackTrace:
"at Amazon.Runtime.Internal.HttpErrorResponseExceptionHandler.HandleException(IExecutionContext executionContext, HttpErrorResponseException exception)
   at Amazon.Runtime.Internal.ErrorHandler.ProcessException(IExecutionContext executionContext, Exception exception)
   at Amazon.Runtime.Internal.ErrorHandler.<InvokeAsync>d__5`1.MoveNext()

When to upgrade

If affected you should upgrade immediately.

Where to get it

You can install NServiceBus.AmazonSQS 5.4 from NuGet.

With thanks,
The team in Particular
