Hi everyone,
We’ve just released NServiceBus.Transport.SqlServer 9.0.2 and 8.1.13.
Fixed bugs
- #1737 Concurrent delayed delivery backoff scheduling race
- #1736 Receive latch may double-signal
- #1735 PostgreSQL table and column existence check may prevent proper table installation
How to know if you are affected
You are affected by #1737 if you use delayed delivery.
You are affected by #1736 if you use version 8.1.11, 8.1.12, 9.0.0, or 9.0.1.
You are affected by #1735 if you use the PostgreSQL transport with automatic table creation or with the transport’s migration scripts.
Symptoms
For #1737, delayed messages may be dispatched later than expected when multiple delayed messages become due while the delayed delivery processor is calculating or waiting for the next execution time.
For #1736, the receive loop may query the database more frequently than expected, especially when horizontally scaling endpoints.
For #1735, PostgreSQL queue tables may not be created or migrated correctly because the table and column existence checks are incorrect.
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.Transport.SqlServer from NuGet.
Please read our release policy for more details.
With thanks,
The team in Particular
