NServiceBus.SqlServer 6.3.4 – Patch release available

Hi everyone,

We’ve just released NServiceBus.SqlServer 6.3.4.

Fixed bugs

  • #1028 Minimize deadlocks on moving delayed messages

How to know if you are affected

You are affected if you use SQL Server transport with scaled-out endpoints.


When scaled out, deadlocks may occur when moving messages from delay tables to queue tables. The deadlocks do not affect system correctness but can cause unwanted noise in logs.

When to upgrade

You should upgrade during your next maintenance window.

Where to get it

You can install NServiceBus.SqlServer 6.3.4 from NuGet.

With thanks,
The team in Particular
