Hi everyone,
We’ve just released NServiceBus.RabbitMQ 10.1.3 and 10.0.4.
Fixed bugs
- #1622 Channel leak or exhaustion with NServiceBus.RabbitMQ 10.x during mass publish
How to know if you are affected
You are affected if:
- Using NServiceBus.RabbitMQ 10.x
- Sending/publishing multiple messages concurrently using the message session
- Sending/publishing multiple messages in a handler
- Sending/publishing multiple messages in a handler with immediate dispatch
Symptoms
When sending multiple messages using NServiceBus.RabbitMQ 10.x, a new channel is created for each message, but these channels are not properly disposed. As a result, channels accumulate and remain open until the endpoint is restarted. In some cases, this leads to the channel_max limit enforced by RabbitMQ (default: 2047) being exceeded, causing subsequent message operations to fail and requiring a restart of the endpoint.
When to upgrade
You should upgrade immediately if you are affected. Otherwise, you should upgrade during your next maintenance window.
Where to get it
You can install the new versions of NServiceBus.RabbitMQ from NuGet.
Please read our release policy for more details.
With thanks,
The team in Particular
