Hi everyone,
We’ve just released NServiceBus 8.1.6 and 8.0.8.
Fixed bugs
- #6909 Combining the outbox with a message-driven transport may lead to message loss when publishing to multiple subscribers
How to know if you are affected
You are affected if one of these conditions apply:
- You are using a message-driven transport like MSMQ or Azure Storage Queues in combination with the outbox
- You are using the transactional session in combination with a message-driven transport like MSMQ or Azure Storage Queues and the outbox
- You are extending the routing stage (e.g.
Behavior<IRoutingContext>) of the message pipeline with custom routing strategies that manipulate headers - You are extending the dispatch stage (e.g.
Behavior<IDispatchContext>) of the message pipeline with behaviours that modify outgoing transport operations
Symptoms
- When publishing an event to multiple subscribers only one of the subscribers receives the event. The subscriber that gets the event gets multiple copies of the same event.
- When either the routing or the dispatch stage is extended, modifications to the headers will be applied to all related outgoing operations instead.
When to upgrade
You should upgrade immediately if you are using MSMQ or Azure Storage Queues transports or if you are extending the NServiceBus pipeline with behaviors in the IRoutingContext and IDispatchContext.
Where to get it
You can install the new versions of NServiceBus from NuGet.
With thanks,
The team in Particular
